QCustomPlot holds an ordered list of - one or more instances of QCPLayer (see QCustomPlot::addLayer, QCustomPlot::layer, - QCustomPlot::moveLayer, etc.). When replotting, QCustomPlot goes through the list of layers - bottom to top and successively draws the layerables of the layers into the paint buffer(s). - - A QCPLayer contains an ordered list of QCPLayerable instances. QCPLayerable is an abstract base - class from which almost all visible objects derive, like axes, grids, graphs, items, etc. - - \section qcplayer-defaultlayers Default layers - - Initially, QCustomPlot has six layers: "background", "grid", "main", "axes", "legend" and - "overlay" (in that order). On top is the "overlay" layer, which only contains the QCustomPlot's - selection rect (\ref QCustomPlot::selectionRect). The next two layers "axes" and "legend" contain - the default axes and legend, so they will be drawn above plottables. In the middle, there is the - "main" layer. It is initially empty and set as the current layer (see - QCustomPlot::setCurrentLayer). This means, all new plottables, items etc. are created on this - layer by default. Then comes the "grid" layer which contains the QCPGrid instances (which belong - tightly to QCPAxis, see \ref QCPAxis::grid). The Axis rect background shall be drawn behind - everything else, thus the default QCPAxisRect instance is placed on the "background" layer. Of - course, the layer affiliation of the individual objects can be changed as required (\ref - QCPLayerable::setLayer). - - \section qcplayer-ordering Controlling the rendering order via layers - - Controlling the ordering of layerables in the plot is easy: Create a new layer in the position - you want the layerable to be in, e.g. above "main", with \ref QCustomPlot::addLayer. Then set the - current layer with \ref QCustomPlot::setCurrentLayer to that new layer and finally create the - objects normally. They will be placed on the new layer automatically, due to the current layer - setting. Alternatively you could have also ignored the current layer setting and just moved the - objects with \ref QCPLayerable::setLayer to the desired layer after creating them. - - It is also possible to move whole layers. For example, If you want the grid to be shown in front - of all plottables/items on the "main" layer, just move it above "main" with - QCustomPlot::moveLayer. - - The rendering order within one layer is simply by order of creation or insertion. The item - created last (or added last to the layer), is drawn on top of all other objects on that layer. - - When a layer is deleted, the objects on it are not deleted with it, but fall on the layer below - the deleted layer, see QCustomPlot::removeLayer. - - \section qcplayer-buffering Replotting only a specific layer - - If the layer mode (\ref setMode) is set to \ref lmBuffered, you can replot only this specific - layer by calling \ref replot. In certain situations this can provide better replot performance, - compared with a full replot of all layers. Upon creation of a new layer, the layer mode is - initialized to \ref lmLogical.

Those - functions are most notably \ref elementCount, \ref elementAt, \ref takeAt, \ref take, \ref - simplify, \ref removeAt, \ref remove and \ref clear. Individual subclasses may add more functions - to this interface which are more specialized to the form of the layout. For example, \ref - QCPLayoutGrid adds functions that take row and column indices to access cells of the layout grid - more conveniently. - - Since this is an abstract base class, you can't instantiate it directly.

- - \section axisticker-subclassing Creating own axis tickers - - Creating own axis tickers can be achieved very easily by sublassing QCPAxisTicker and - reimplementing some or all of the available virtual methods. - - In the simplest case you might wish to just generate different tick steps than the other tickers, - so you only reimplement the method \ref getTickStep. If you additionally want control over the - string that will be shown as tick label, reimplement \ref getTickLabel. - - If you wish to have complete control, you can generate the tick vectors and tick label vectors - yourself by reimplementing \ref createTickVector and \ref createLabelVector. The default - implementations use the previously mentioned virtual methods \ref getTickStep and \ref - getTickLabel, but your reimplementations don't necessarily need to do so. For example in the case - of unequal tick steps, the method \ref getTickStep loses its usefulness and can be ignored. - - The sub tick count between major ticks can be controlled with \ref getSubTickCount. Full sub tick - placement control is obtained by reimplementing \ref createSubTickVector. - - See the documentation of all these virtual methods in QCPAxisTicker for detailed information - about the parameters and expected return values. -*/ - -/*! - Constructs the ticker and sets reasonable default values.

The - plot axis coordinate is interpreted as Unix Time, so seconds since Epoch (January 1, 1970, 00:00 - UTC). This is also used for example by QDateTime in the toTime_t()/setTime_t() methods - with a precision of one second. Since Qt 4.7, millisecond accuracy can be obtained from QDateTime - by using QDateTime::fromMSecsSinceEpoch()/1000.0. The static methods \ref dateTimeToKey - and \ref keyToDateTime conveniently perform this conversion achieving a precision of one - millisecond on all Qt versions. - - The format of the date/time display in the tick labels is controlled with \ref setDateTimeFormat. - If a different time spec or time zone shall be used for the tick label appearance, see \ref - setDateTimeSpec or \ref setTimeZone, respectively. - - This ticker produces unequal tick spacing in order to provide intuitive date and time-of-day - ticks. For example, if the axis range spans a few years such that there is one tick per year, - ticks will be positioned on 1. January of every year. This is intuitive but, due to leap years, - will result in slightly unequal tick intervals (visually unnoticeable). The same can be seen in - the image above: even though the number of days varies month by month, this ticker generates - ticks on the same day of each month. - - If you would like to change the date/time that is used as a (mathematical) starting date for the - ticks, use the \ref setTickOrigin(const QDateTime &origin) method overload, which takes a - QDateTime. If you pass 15. July, 9:45 to this method, the yearly ticks will end up on 15. July at - 9:45 of every year. - - The ticker can be created and assigned to an axis like this: - \snippet documentation/doc-image-generator/mainwindow.cpp axistickerdatetime-creation - - \note If you rather wish to display relative times in terms of days, hours, minutes, seconds and - milliseconds, and are not interested in the intricacies of real calendar dates with months and - (leap) years, have a look at QCPAxisTickerTime instead. -*/ - -/*! - Constructs the ticker and sets reasonable default values.

This \a formatCode is an extended version - of the format code used e.g. by QString::number() and QLocale::toString(). For reference about - that, see the "Argument Formats" section in the detailed description of the QString class. - - \a formatCode is a string of one, two or three characters. - - The first character is identical to - the normal format code used by Qt. In short, this means: 'e'/'E' scientific format, 'f' fixed - format, 'g'/'G' scientific or fixed, whichever is shorter. For the 'e', 'E', and 'f' formats, - the precision set by \ref setNumberPrecision represents the number of digits after the decimal - point. For the 'g' and 'G' formats, the precision represents the maximum number of significant - digits, trailing zeroes are omitted. - - The second and third characters are optional and specific to QCustomPlot:\n - If the first char was 'e' or 'g', numbers are/might be displayed in the scientific format, e.g. - "5.5e9", which is ugly in a plot. So when the second char of \a formatCode is set to 'b' (for - "beautiful"), those exponential numbers are formatted in a more natural way, i.e. "5.5 - [multiplication sign] 10 [superscript] 9". By default, the multiplication sign is a centered dot. - If instead a cross should be shown (as is usual in the USA), the third char of \a formatCode can - be set to 'c'. The inserted multiplication signs are the UTF-8 characters 215 (0xD7) for the - cross and 183 (0xB7) for the dot. - - Examples for \a formatCode: - \li \c g normal format code behaviour. If number is small, fixed format is used, if number is large, - normal scientific format is used - \li \c gb If number is small, fixed format is used, if number is large, scientific format is used with - beautifully typeset decimal powers and a dot as multiplication sign - \li \c ebc All numbers are in scientific format with beautifully typeset decimal power and a cross as - multiplication sign - \li \c fb illegal format code, since fixed format doesn't support (or need) beautifully typeset decimal - powers. Format code will be reduced to 'f'. - \li \c hello illegal format code, since first char is not 'e', 'E', 'f', 'g' or 'G'.

In plottables like - QCPGraph it is used to store how scatter points shall be drawn. For example, \ref - QCPGraph::setScatterStyle takes a QCPScatterStyle instance. - - A scatter style consists of a shape (\ref setShape), a line color (\ref setPen) and possibly a - fill (\ref setBrush), if the shape provides a fillable area. Further, the size of the shape can - be controlled with \ref setSize. - - \section QCPScatterStyle-defining Specifying a scatter style - - You can set all these configurations either by calling the respective functions on an instance: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-1 - - Or you can use one of the various constructors that take different parameter combinations, making - it easy to specify a scatter style in a single call, like so: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-2 - - \section QCPScatterStyle-undefinedpen Leaving the color/pen up to the plottable - - There are two constructors which leave the pen undefined: \ref QCPScatterStyle() and \ref - QCPScatterStyle(ScatterShape shape, double size). If those constructors are used, a call to \ref - isPenDefined will return false. It leads to scatter points that inherit the pen from the - plottable that uses the scatter style. Thus, if such a scatter style is passed to QCPGraph, the line - color of the graph (\ref QCPGraph::setPen) will be used by the scatter points. This makes - it very convenient to set up typical scatter settings: - - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-shortcreation - - Notice that it wasn't even necessary to explicitly call a QCPScatterStyle constructor. This works - because QCPScatterStyle provides a constructor that can transform a \ref ScatterShape directly - into a QCPScatterStyle instance (that's the \ref QCPScatterStyle(ScatterShape shape, double size) - constructor with a default for \a size). In those cases, C++ allows directly supplying a \ref - ScatterShape, where actually a QCPScatterStyle is expected. - - \section QCPScatterStyle-custompath-and-pixmap Custom shapes and pixmaps - - QCPScatterStyle supports drawing custom shapes and arbitrary pixmaps as scatter points. - - For custom shapes, you can provide a QPainterPath with the desired shape to the \ref - setCustomPath function or call the constructor that takes a painter path. The scatter shape will - automatically be set to \ref ssCustom. - - For pixmaps, you call \ref setPixmap with the desired QPixmap. Alternatively you can use the - constructor that takes a QPixmap. The scatter shape will automatically be set to \ref ssPixmap. - Note that \ref setSize does not influence the appearance of the pixmap. -*/ - -/* start documentation of inline functions */ - -/*! \fn bool QCPScatterStyle::isNone() const - - Returns whether the scatter shape is \ref ssNone. - - \see setShape -*/ - -/*! \fn bool QCPScatterStyle::isPenDefined() const - - Returns whether a pen has been defined for this scatter style. - - The pen is undefined if a constructor is called that does not carry \a pen as parameter.

If you are worried about performance (i.e. you need - to translate many points in a loop like QCPGraph), you can directly use \ref - QCPAxis::coordToPixel.

QCustomPlot *\b mParentPlotA pointer to the parent QCustomPlot instance. The parent plot is inferred from the axes that are passed in the constructor.
QString \b mNameThe name of the plottable.
QPen \b mPenThe generic pen of the plottable. You should use this pen for the most prominent data representing lines in the plottable - (e.g QCPGraph uses this pen for its graph lines and scatters)
QBrush \b mBrushThe generic brush of the plottable. You should use this brush for the most prominent fillable structures in the plottable - (e.g. QCPGraph uses this brush to control filling under the graph)
QPointer<\ref QCPAxis> \b mKeyAxis, \b mValueAxisThe key and value axes this plottable is attached to. Call their QCPAxis::coordToPixel functions to translate coordinates - to pixels in either the key or value dimension. Make sure to check whether the pointer is \c nullptr before using it. If one of - the axes is null, don't draw the plottable.
\ref QCPSelectionDecorator \b mSelectionDecoratorThe currently set selection decorator which specifies how selected data of the plottable shall be drawn and decorated. - When drawing your data, you must consult this decorator for the appropriate pen/brush before drawing unselected/selected data segments. - Finally, you should call its \ref QCPSelectionDecorator::drawDecoration method at the end of your \ref draw implementation.
\ref QCP::SelectionType \b mSelectableIn which composition, if at all, this plottable's data may be selected. Enforcing this setting on the data selection is done - by QCPAbstractPlottable automatically.

Some items have multiple positions, for example QCPItemRect has two: - \a topLeft and \a bottomRight. - - QCPItemPosition has a type (\ref PositionType) that can be set with \ref setType. This type - defines how coordinates passed to \ref setCoords are to be interpreted, e.g. as absolute pixel - coordinates, as plot coordinates of certain axes (\ref QCPItemPosition::setAxes), as fractions of - the axis rect (\ref QCPItemPosition::setAxisRect), etc. For more advanced plots it is also - possible to assign different types per X/Y coordinate of the position (see \ref setTypeX, \ref - setTypeY). This way an item could be positioned for example at a fixed pixel distance from the - top in the Y direction, while following a plot coordinate in the X direction. - - A QCPItemPosition may have a parent QCPItemAnchor, see \ref setParentAnchor. This way you can tie - multiple items together. If the QCPItemPosition has a parent, its coordinates (\ref setCoords) - are considered to be absolute pixels in the reference frame of the parent anchor, where (0, 0) - means directly ontop of the parent anchor. For example, You could attach the \a start position of - a QCPItemLine to the \a bottom anchor of a QCPItemText to make the starting point of the line - always be centered under the text label, no matter where the text is moved to. For more advanced - plots, it is possible to assign different parent anchors per X/Y coordinate of the position, see - \ref setParentAnchorX, \ref setParentAnchorY. This way an item could follow another item in the X - direction but stay at a fixed position in the Y direction. Or even follow item A in X, and item B - in Y. - - Note that every QCPItemPosition inherits from QCPItemAnchor and thus can itself be used as parent - anchor for other positions. - - To set the apparent pixel position on the QCustomPlot surface directly, use \ref setPixelPosition.

While plottables are always tied to two axes and thus - plot coordinates, items can also be placed in absolute coordinates independent of any axes. Each - specific item has at least one QCPItemPosition member which controls the positioning. Some items - are defined by more than one coordinate and thus have two or more QCPItemPosition members (For - example, QCPItemRect has \a topLeft and \a bottomRight). - - This abstract base class defines a very basic interface like visibility and clipping. Since this - class is abstract, it can't be instantiated. Use one of the subclasses or create a subclass - yourself to create new items. - - The built-in items are: - - - - - - - - - - -
QCPItemLineA line defined by a start and an end point. May have different ending styles on each side (e.g. arrows).
QCPItemStraightLineA straight line defined by a start and a direction point. Unlike QCPItemLine, the straight line is infinitely long and has no endings.
QCPItemCurveA curve defined by start, end and two intermediate control points. May have different ending styles on each side (e.g. arrows).
QCPItemRectA rectangle
QCPItemEllipseAn ellipse
QCPItemPixmapAn arbitrary pixmap
QCPItemTextA text label
QCPItemBracketA bracket which may be used to reference/highlight certain parts in the plot.
QCPItemTracerAn item that can be attached to a QCPGraph and sticks to its data points, given a key coordinate.
- - \section items-clipping Clipping - - Items are by default clipped to the main axis rect (they are only visible inside the axis rect). - To make an item visible outside that axis rect, disable clipping via \ref setClipToAxisRect - "setClipToAxisRect(false)". - - On the other hand if you want the item to be clipped to a different axis rect, specify it via - \ref setClipAxisRect. This clipAxisRect property of an item is only used for clipping behaviour, and - in principle is independent of the coordinate axes the item might be tied to via its position - members (\ref QCPItemPosition::setAxes). However, it is common that the axis rect for clipping - also contains the axes used for the item positions. - - \section items-using Using items - - First you instantiate the item you want to use and add it to the plot: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-1 - by default, the positions of the item are bound to the x- and y-Axis of the plot. So we can just - set the plot coordinates where the line should start/end: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-2 - If we don't want the line to be positioned in plot coordinates but a different coordinate system, - e.g. absolute pixel positions on the QCustomPlot surface, we need to change the position type like this: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-3 - Then we can set the coordinates, this time in pixels: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-4 - and make the line visible on the entire QCustomPlot, by disabling clipping to the axis rect: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-5 - - For more advanced plots, it is even possible to set different types and parent anchors per X/Y - coordinate of an item position, using for example \ref QCPItemPosition::setTypeX or \ref - QCPItemPosition::setParentAnchorX. For details, see the documentation of \ref QCPItemPosition. - - \section items-subclassing Creating own items - - To create an own item, you implement a subclass of QCPAbstractItem. These are the pure - virtual functions, you must implement: - \li \ref selectTest - \li \ref draw - - See the documentation of those functions for what they need to do. - - \subsection items-positioning Allowing the item to be positioned - - As mentioned, item positions are represented by QCPItemPosition members. Let's assume the new item shall - have only one point as its position (as opposed to two like a rect or multiple like a polygon). You then add - a public member of type QCPItemPosition like so: - - \code QCPItemPosition * const myPosition;\endcode - - the const makes sure the pointer itself can't be modified from the user of your new item (the QCPItemPosition - instance it points to, can be modified, of course). - The initialization of this pointer is made easy with the \ref createPosition function. Just assign - the return value of this function to each QCPItemPosition in the constructor of your item. \ref createPosition - takes a string which is the name of the position, typically this is identical to the variable name. - For example, the constructor of QCPItemExample could look like this: - - \code - QCPItemExample::QCPItemExample(QCustomPlot *parentPlot) : - QCPAbstractItem(parentPlot), - myPosition(createPosition("myPosition")) - { - // other constructor code - } - \endcode - - \subsection items-drawing The draw function - - To give your item a visual representation, reimplement the \ref draw function and use the passed - QCPPainter to draw the item. You can retrieve the item position in pixel coordinates from the - position member(s) via \ref QCPItemPosition::pixelPosition. - - To optimize performance you should calculate a bounding rect first (don't forget to take the pen - width into account), check whether it intersects the \ref clipRect, and only draw the item at all - if this is the case. - - \subsection items-selection The selectTest function - - Your implementation of the \ref selectTest function may use the helpers \ref - QCPVector2D::distanceSquaredToLine and \ref rectDistance. With these, the implementation of the - selection test becomes significantly simpler for most items. See the documentation of \ref - selectTest for what the function parameters mean and what the function should return. - - \subsection anchors Providing anchors - - Providing anchors (QCPItemAnchor) starts off like adding a position. First you create a public - member, e.g. - - \code QCPItemAnchor * const bottom;\endcode - - and create it in the constructor with the \ref createAnchor function, assigning it a name and an - anchor id (an integer enumerating all anchors on the item, you may create an own enum for this). - Since anchors can be placed anywhere, relative to the item's position(s), your item needs to - provide the position of every anchor with the reimplementation of the \ref anchorPixelPosition(int - anchorId) function. - - In essence the QCPItemAnchor is merely an intermediary that itself asks your item for the pixel - position when anything attached to the anchor needs to know the coordinates. -*/ - -/* start of documentation of inline functions */ - -/*! \fn QList QCPAbstractItem::positions() const - - Returns all positions of the item in a list. - - \see anchors, position -*/ - -/*! \fn QList QCPAbstractItem::anchors() const - - Returns all anchors of the item in a list.

However, the - layout system allows to have multiple axis rects, e.g. arranged in a grid layout - (QCustomPlot::plotLayout). - - By default, QCPAxisRect comes with four axes, at bottom, top, left and right. They can be - accessed via \ref axis by providing the respective axis type (\ref QCPAxis::AxisType) and index. - If you need all axes in the axis rect, use \ref axes. The top and right axes are set to be - invisible initially (QCPAxis::setVisible). To add more axes to a side, use \ref addAxis or \ref - addAxes. To remove an axis, use \ref removeAxis. - - The axis rect layerable itself only draws a background pixmap or color, if specified (\ref - setBackground). It is placed on the "background" layer initially (see \ref QCPLayer for an - explanation of the QCustomPlot layer system). The axes that are held by the axis rect can be - placed on other layers, independently of the axis rect. - - Every axis rect has a child layout of type \ref QCPLayoutInset. It is accessible via \ref - insetLayout and can be used to have other layout elements (or even other layouts with multiple - elements) hovering inside the axis rect. - - If an axis rect is clicked and dragged, it processes this by moving certain axis ranges. The - behaviour can be controlled with \ref setRangeDrag and \ref setRangeDragAxes. If the mouse wheel - is scrolled while the cursor is on the axis rect, certain axes are scaled. This is controllable - via \ref setRangeZoom, \ref setRangeZoomAxes and \ref setRangeZoomFactor. These interactions are - only enabled if \ref QCustomPlot::setInteractions contains \ref QCP::iRangeDrag and \ref - QCP::iRangeZoom. - - \image html AxisRectSpacingOverview.png -

In the case of the main legend (\ref - QCustomPlot::legend), simply adding plottables to the plot while \ref - QCustomPlot::setAutoAddPlottableToLegend is set to true (the default) creates corresponding - legend items. The legend item associated with a certain plottable can be removed with \ref - QCPAbstractPlottable::removeFromLegend. However, QCPLegend also offers an interface to add and - manipulate legend items directly: \ref item, \ref itemWithPlottable, \ref itemCount, \ref - addItem, \ref removeItem, etc. - - Since \ref QCPLegend derives from \ref QCPLayoutGrid, it can be placed in any position a \ref - QCPLayoutElement may be positioned. The legend items are themselves \ref QCPLayoutElement - "QCPLayoutElements" which are placed in the grid layout of the legend. \ref QCPLegend only adds - an interface specialized for handling child elements of type \ref QCPAbstractLegendItem, as - mentioned above. In principle, any other layout elements may also be added to a legend via the - normal \ref QCPLayoutGrid interface. See the special page about \link thelayoutsystem The Layout - System\endlink for examples on how to add other elements to the legend and move it outside the axis - rect. - - Use the methods \ref setFillOrder and \ref setWrap inherited from \ref QCPLayoutGrid to control - in which order (column first or row first) the legend is filled up when calling \ref addItem, and - at which column or row wrapping occurs. The default fill order for legends is \ref foRowsFirst. - - By default, every QCustomPlot has one legend (\ref QCustomPlot::legend) which is placed in the - inset layout of the main axis rect (\ref QCPAxisRect::insetLayout). To move the legend to another - position inside the axis rect, use the methods of the \ref QCPLayoutInset. To move the legend - outside of the axis rect, place it anywhere else with the \ref QCPLayout/\ref QCPLayoutElement - interface. -*/ - -/* start of documentation of signals */ - -/*! \fn void QCPLegend::selectionChanged(QCPLegend::SelectableParts selection); - - This signal is emitted when the selection state of this legend has changed. - - \see setSelectedParts, setSelectableParts -*/ - -/* end of documentation of signals */ - -/*! - Constructs a new QCPLegend instance with default values. - - Note that by default, QCustomPlot already contains a legend ready to be used as \ref - QCustomPlot::legend -*/ -QCPLegend::QCPLegend() : - mIconTextPadding{} -{ - setFillOrder(QCPLayoutGrid::foRowsFirst); - setWrap(0); - - setRowSpacing(3); - setColumnSpacing(8); - setMargins(QMargins(7, 5, 7, 4)); - setAntialiased(false); - setIconSize(32, 18); - - setIconTextPadding(7); - - setSelectableParts(spLegendBox | spItems); - setSelectedParts(spNone); - - setBorderPen(QPen(Qt::black, 0)); - setSelectedBorderPen(QPen(Qt::blue, 2)); - setIconBorderPen(Qt::NoPen); - setSelectedIconBorderPen(QPen(Qt::blue, 2)); - setBrush(Qt::white); - setSelectedBrush(Qt::white); - setTextColor(Qt::black); - setSelectedTextColor(Qt::blue); -} - -QCPLegend::~QCPLegend() -{ - clearItems(); - if (qobject_cast(mParentPlot)) // make sure this isn't called from QObject dtor when QCustomPlot is already destructed (happens when the legend is not in any layout and thus QObject-child of QCustomPlot) - mParentPlot->legendRemoved(this); -} - -/* no doc for getter, see setSelectedParts */ -QCPLegend::SelectableParts QCPLegend::selectedParts() const -{ - // check whether any legend elements selected, if yes, add spItems to return value - bool hasSelectedItems = false; - for (int i=0; iselected()) - { - hasSelectedItems = true; - break; - } - } - if (hasSelectedItems) - return mSelectedParts | spItems; - else - return mSelectedParts & ~spItems; -} - -/*! - Sets the pen, the border of the entire legend is drawn with. -*/ -void QCPLegend::setBorderPen(const QPen &pen) -{ - mBorderPen = pen; -} - -/*! - Sets the brush of the legend background. -*/ -void QCPLegend::setBrush(const QBrush &brush) -{ - mBrush = brush; -} - -/*! - Sets the default font of legend text.

It - is usually used in combination with one or multiple \ref QCPColorMap "QCPColorMaps". - - \image html QCPColorScale.png - - The color scale can be either horizontal or vertical, as shown in the image above. The - orientation and the side where the numbers appear is controlled with \ref setType. - - Use \ref QCPColorMap::setColorScale to connect a color map with a color scale. Once they are - connected, they share their gradient, data range and data scale type (\ref setGradient, \ref - setDataRange, \ref setDataScaleType). Multiple color maps may be associated with a single color - scale, to make them all synchronize these properties. - - To have finer control over the number display and axis behaviour, you can directly access the - \ref axis. See the documentation of QCPAxis for details about configuring axes. For example, if - you want to change the number of automatically generated ticks, call - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-tickcount - - Placing a color scale next to the main axis rect works like with any other layout element: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-creation - In this case we have placed it to the right of the default axis rect, so it wasn't necessary to - call \ref setType, since \ref QCPAxis::atRight is already the default. The text next to the color - scale can be set with \ref setLabel. - - For optimum appearance (like in the image above), it may be desirable to line up the axis rect and - the borders of the color scale. Use a \ref QCPMarginGroup to achieve this: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-margingroup - - Color scales are initialized with a non-zero minimum top and bottom margin (\ref - setMinimumMargins), because vertical color scales are most common and the minimum top/bottom - margin makes sure it keeps some distance to the top/bottom widget border. So if you change to a - horizontal color scale by setting \ref setType to \ref QCPAxis::atBottom or \ref QCPAxis::atTop, you - might want to also change the minimum margins accordingly, e.g. setMinimumMargins(QMargins(6, 0, 6, 0)). -*/ - -/* start documentation of inline functions */ - -/*! \fn QCPAxis *QCPColorScale::axis() const - - Returns the internal \ref QCPAxis instance of this color scale.

It holds a two-dimensional array, which \ref - QCPColorMap then displays as a 2D image in the plot, where the array values are represented by a - color, depending on the value. - - The size of the array can be controlled via \ref setSize (or \ref setKeySize, \ref setValueSize). - Which plot coordinates these cells correspond to can be configured with \ref setRange (or \ref - setKeyRange, \ref setValueRange). - - The data cells can be accessed in two ways: They can be directly addressed by an integer index - with \ref setCell. This is the fastest method. Alternatively, they can be addressed by their plot - coordinate with \ref setData. plot coordinate to cell index transformations and vice versa are - provided by the functions \ref coordToCell and \ref cellToCoord. - - A \ref QCPColorMapData also holds an on-demand two-dimensional array of alpha values which (if - allocated) has the same size as the data map. It can be accessed via \ref setAlpha, \ref - fillAlpha and \ref clearAlpha. The memory for the alpha map is only allocated if needed, i.e. on - the first call of \ref setAlpha. \ref clearAlpha restores full opacity and frees the alpha map. - - This class also buffers the minimum and maximum values that are in the data set, to provide - QCPColorMap::rescaleDataRange with the necessary information quickly. Setting a cell to a value - that is greater than the current maximum increases this maximum to the new value. However, - setting the cell that currently holds the maximum value to a smaller value doesn't decrease the - maximum again, because finding the true new maximum would require going through the entire data - array, which might be time consuming. The same holds for the data minimum. This functionality is - given by \ref recalculateDataBounds, such that you can decide when it is sensible to find the - true current minimum and maximum.

As with other plottables such as graphs, \a key and \a value - correspond to two orthogonal axes on the QCustomPlot surface that you specify in the QCPColorMap - constructor. The \a data dimension however is encoded as the color of the point at (\a key, \a - value). - - Set the number of points (or \a cells) in the key/value dimension via \ref - QCPColorMapData::setSize. The plot coordinate range over which these points will be displayed is - specified via \ref QCPColorMapData::setRange. The first cell will be centered on the lower range - boundary and the last cell will be centered on the upper range boundary. The data can be set by - either accessing the cells directly with QCPColorMapData::setCell or by addressing the cells via - their plot coordinates with \ref QCPColorMapData::setData. If possible, you should prefer - setCell, since it doesn't need to do any coordinate transformation and thus performs a bit - better. - - The cell with index (0, 0) is at the bottom left, if the color map uses normal (i.e. not reversed) - key and value axes. - - To show the user which colors correspond to which \a data values, a \ref QCPColorScale is - typically placed to the right of the axis rect. See the documentation there for details on how to - add and use a color scale. - - \section qcpcolormap-appearance Changing the appearance - - Most important to the appearance is the color gradient, which can be specified via \ref - setGradient. See the documentation of \ref QCPColorGradient for details on configuring a color - gradient. - - The \a data range that is mapped to the colors of the gradient can be specified with \ref - setDataRange. To make the data range encompass the whole data set minimum to maximum, call \ref - rescaleDataRange. If your data may contain NaN values, use \ref QCPColorGradient::setNanHandling - to define how they are displayed. - - \section qcpcolormap-transparency Transparency - - Transparency in color maps can be achieved by two mechanisms. On one hand, you can specify alpha - values for color stops of the \ref QCPColorGradient, via the regular QColor interface. This will - cause the color map data which gets mapped to colors around those color stops to appear with the - accordingly interpolated transparency. - - On the other hand you can also directly apply an alpha value to each cell independent of its - data, by using the alpha map feature of \ref QCPColorMapData. The relevant methods are \ref - QCPColorMapData::setAlpha, QCPColorMapData::fillAlpha and \ref QCPColorMapData::clearAlpha(). - - The two transparencies will be joined together in the plot and otherwise not interfere with each - other. They are mixed in a multiplicative matter, so an alpha of e.g. 50% (128/255) in both modes - simultaneously, will result in a total transparency of 25% (64/255). - - \section qcpcolormap-usage Usage - - Like all data representing objects in QCustomPlot, the QCPColorMap is a plottable - (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies - (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.) - - Usually, you first create an instance: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-1 - which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes - ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead. - The newly created plottable can be modified, e.g.: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-2 - - \note The QCPColorMap always displays the data at equal key/value intervals, even if the key or - value axis is set to a logarithmic scaling. If you want to use QCPColorMap with logarithmic axes, - you shouldn't use the \ref QCPColorMapData::setData method as it uses a linear transformation to - determine the cell index.

The two common representations OHLC (Open-High-Low-Close) bars and Candlesticks can be - set via \ref setChartStyle. - - The data is passed via \ref setData as a set of open/high/low/close values at certain keys - (typically times). This means the data must be already binned appropriately. If data is only - available as a series of values (e.g. \a price against \a time), you can use the static - convenience function \ref timeSeriesToOhlc to generate binned OHLC-data which can then be passed - to \ref setData. - - The width of the OHLC bars/candlesticks can be controlled with \ref setWidth and \ref - setWidthType. A typical choice is to set the width type to \ref wtPlotCoords (the default) and - the width to (or slightly less than) one time bin interval width. - - \section qcpfinancial-appearance Changing the appearance - - Charts can be either single- or two-colored (\ref setTwoColored). If set to be single-colored, - lines are drawn with the plottable's pen (\ref setPen) and fills with the brush (\ref setBrush). - - If set to two-colored, positive changes of the value during an interval (\a close >= \a open) are - represented with a different pen and brush than negative changes (\a close < \a open). These can - be configured with \ref setPenPositive, \ref setPenNegative, \ref setBrushPositive, and \ref - setBrushNegative. In two-colored mode, the normal plottable pen/brush is ignored. Upon selection - however, the normal selected pen/brush (provided by the \ref selectionDecorator) is used, - irrespective of whether the chart is single- or two-colored. - - \section qcpfinancial-usage Usage - - Like all data representing objects in QCustomPlot, the QCPFinancial is a plottable - (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies - (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.) - - Usually, you first create an instance: - - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-1 - which registers it with the QCustomPlot instance of the passed axes.

The newly created plottable can be modified, e.g.: - - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-2 - Here we have used the static helper method \ref timeSeriesToOhlc, to turn a time-price data - series into a 24-hour binned open-high-low-close data series as QCPFinancial uses. -*/ - -/* start of documentation of inline functions */ - -/*! \fn QCPFinancialDataContainer *QCPFinancial::data() const - - Returns a pointer to the internal data storage of type \ref QCPFinancialDataContainer.

\class QCPDataContainer - \brief The generic data container for one-dimensional plottables - - This class template provides a fast container for data storage of one-dimensional data. The data - type is specified as template parameter (called \a DataType in the following) and must provide - some methods as described in the \ref qcpdatacontainer-datatype "next section". - - The data is stored in a sorted fashion, which allows very quick lookups by the sorted key as well - as retrieval of ranges (see \ref findBegin, \ref findEnd, \ref keyRange) using binary search. The - container uses a preallocation and a postallocation scheme, such that appending and prepending - data (with respect to the sort key) is very fast and minimizes reallocations. If data is added - which needs to be inserted between existing keys, the merge usually can be done quickly too, - using the fact that existing data is always sorted. The user can further improve performance by - specifying that added data is already itself sorted by key, if he can guarantee that this is the - case (see for example \ref add(const QVector &data, bool alreadySorted)). - - The data can be accessed with the provided const iterators (\ref constBegin, \ref constEnd). If - it is necessary to alter existing data in-place, the non-const iterators can be used (\ref begin, - \ref end). Changing data members that are not the sort key (for most data types called \a key) is - safe from the container's perspective. - - Great care must be taken however if the sort key is modified through the non-const iterators. For - performance reasons, the iterators don't automatically cause a re-sorting upon their - manipulation. It is thus the responsibility of the user to leave the container in a sorted state - when finished with the data manipulation, before calling any other methods on the container. A - complete re-sort (e.g. after finishing all sort key manipulation) can be done by calling \ref - sort. Failing to do so can not be detected by the container efficiently and will cause both - rendering artifacts and potential data loss. - - Implementing one-dimensional plottables that make use of a \ref QCPDataContainer is usually - done by subclassing from \ref QCPAbstractPlottable1D "QCPAbstractPlottable1D", which - introduces an according \a mDataContainer member and some convenience methods. - - \section qcpdatacontainer-datatype Requirements for the DataType template parameter - - The template parameter DataType is the type of the stored data points. It must be - trivially copyable and have the following public methods, preferably inline: - - \li double sortKey() const\n Returns the member variable of this data point that is the - sort key, defining the ordering in the container. Often this variable is simply called \a key. - - \li static DataType fromSortKey(double sortKey)\n Returns a new instance of the data - type initialized with its sort key set to \a sortKey. - - \li static bool sortKeyIsMainKey()\n Returns true if the sort key is equal to the main - key (see method \c mainKey below). For most plottables this is the case. It is not the case for - example for \ref QCPCurve, which uses \a t as sort key and \a key as main key. This is the reason - why QCPCurve unlike QCPGraph can display parametric curves with loops. - - \li double mainKey() const\n Returns the variable of this data point considered the main - key. This is commonly the variable that is used as the coordinate of this data point on the key - axis of the plottable. This method is used for example when determining the automatic axis - rescaling of key axes (\ref QCPAxis::rescale). - - \li double mainValue() const\n Returns the variable of this data point considered the - main value. This is commonly the variable that is used as the coordinate of this data point on - the value axis of the plottable. - - \li QCPRange valueRange() const\n Returns the range this data point spans in the value - axis coordinate. If the data is single-valued (e.g. QCPGraphData), this is simply a range with - both lower and upper set to the main data point value. However if the data points can represent - multiple values at once (e.g QCPFinancialData with its \a high, \a low, \a open and \a close - values at each \a key) this method should return the range those values span. This method is used - for example when determining the automatic axis rescaling of value axes (\ref - QCPAxis::rescale). -*/ - -/* start documentation of inline functions */ - -/*! \fn int QCPDataContainer::size() const - - Returns the number of data points in the container. -*/ - -/*! \fn bool QCPDataContainer::isEmpty() const - - Returns whether this container holds no data points. -*/ - -/*! \fn QCPDataContainer::const_iterator QCPDataContainer::constBegin() const - - Returns a const iterator to the first data point in this container. -*/ - -/*! \fn QCPDataContainer::const_iterator QCPDataContainer::constEnd() const - - Returns a const iterator to the element past the last data point in this container. -*/ - -/*! \fn QCPDataContainer::iterator QCPDataContainer::begin() const - - Returns a non-const iterator to the first data point in this container. - - You can manipulate the data points in-place through the non-const iterators, but great care must - be taken when manipulating the sort key of a data point, see \ref sort, or the detailed - description of this class. -*/ - -/*! \fn QCPDataContainer::iterator QCPDataContainer::end() const - - Returns a non-const iterator to the element past the last data point in this container. - - You can manipulate the data points in-place through the non-const iterators, but great care must - be taken when manipulating the sort key of a data point, see \ref sort, or the detailed - description of this class. -*/ - -/*! \fn QCPDataContainer::const_iterator QCPDataContainer::at(int index) const - - Returns a const iterator to the element with the specified \a index.

It serves as a base class for all one-dimensional data (i.e. data with - one key dimension), such as \ref QCPGraph and QCPCurve. - - The template parameter \a DataType is the type of the data points of this plottable (e.g. \ref - QCPGraphData or \ref QCPCurveData). The main purpose of this base class is to provide the member - \a mDataContainer (a shared pointer to a \ref QCPDataContainer "QCPDataContainer") and - implement the according virtual methods of the \ref QCPPlottableInterface1D, such that most - subclassed plottables don't need to worry about this anymore. - - Further, it provides a convenience method for retrieving selected/unselected data segments via - \ref getDataSegments. This is useful when subclasses implement their \ref draw method and need to - draw selected segments with a different pen/brush than unselected segments (also see \ref - QCPSelectionDecorator). - - This class implements basic functionality of \ref QCPAbstractPlottable::selectTest and \ref - QCPPlottableInterface1D::selectTestRect, assuming point-like data points, based on the 1D data - interface. In spite of that, most plottable subclasses will want to reimplement those methods - again, to provide a more accurate hit test based on their specific data visualization geometry. -*/ - -/* start documentation of inline functions */ - -/*! \fn QCPPlottableInterface1D *QCPAbstractPlottable1D::interface1D() - - Returns a \ref QCPPlottableInterface1D pointer to this plottable, providing access to its 1D - interface. - - \seebaseclassmethod -*/ - -/* end documentation of inline functions */ - -/*! - Forwards \a keyAxis and \a valueAxis to the \ref QCPAbstractPlottable::QCPAbstractPlottable - "QCPAbstractPlottable" constructor and allocates the \a mDataContainer. -*/ -template -QCPAbstractPlottable1D::QCPAbstractPlottable1D(QCPAxis *keyAxis, QCPAxis *valueAxis) : - QCPAbstractPlottable(keyAxis, valueAxis), - mDataContainer(new QCPDataContainer) -{ -} - -template -QCPAbstractPlottable1D::~QCPAbstractPlottable1D() -{ -} - -/*! - \copydoc QCPPlottableInterface1D::dataCount -*/ -template -int QCPAbstractPlottable1D::dataCount() const -{ - return mDataContainer->size(); -} - -/*! - \copydoc QCPPlottableInterface1D::dataMainKey -*/ -template -double QCPAbstractPlottable1D::dataMainKey(int index) const -{ - if (index >= 0 && index < mDataContainer->size()) - { - return (mDataContainer->constBegin()+index)->mainKey(); - } else - { - qDebug() << Q_FUNC_INFO << "Index out of bounds" << index; - return 0; - } -} - -/*! - \copydoc QCPPlottableInterface1D::dataSortKey -*/ -template -double QCPAbstractPlottable1D::dataSortKey(int index) const -{ - if (index >= 0 && index < mDataContainer->size()) - { - return (mDataContainer->constBegin()+index)->sortKey(); - } else - { - qDebug() << Q_FUNC_INFO << "Index out of bounds" << index; - return 0; - } -} - -/*! - \copydoc QCPPlottableInterface1D::dataMainValue -*/ -template -double QCPAbstractPlottable1D::dataMainValue(int index) const -{ - if (index >= 0 && index < mDataContainer->size()) - { - return (mDataContainer->constBegin()+index)->mainValue(); - } else - { - qDebug() << Q_FUNC_INFO << "Index out of bounds" << index; - return 0; - } -} - -/*! - \copydoc QCPPlottableInterface1D::dataValueRange -*/ -template -QCPRange QCPAbstractPlottable1D::dataValueRange(int index) const -{ - if (index >= 0 && index < mDataContainer->size()) - { - return (mDataContainer->constBegin()+index)->valueRange(); - } else - { - qDebug() << Q_FUNC_INFO << "Index out of bounds" << index; - return QCPRange(0, 0); - } -} - -/*! - \copydoc QCPPlottableInterface1D::dataPixelPosition -*/ -template -QPointF QCPAbstractPlottable1D::dataPixelPosition(int index) const -{ - if (index >= 0 && index < mDataContainer->size()) - { - const typename QCPDataContainer::const_iterator it = mDataContainer->constBegin()+index; - return coordsToPixels(it->mainKey(), it->mainValue()); - } else - { - qDebug() << Q_FUNC_INFO << "Index out of bounds" << index; - return QPointF(); - } -} - -/*! - \copydoc QCPPlottableInterface1D::sortKeyIsMainKey -*/ -template -bool QCPAbstractPlottable1D::sortKeyIsMainKey() const -{ - return DataType::sortKeyIsMainKey(); -} - -/*! - Implements a rect-selection algorithm assuming the data (accessed via the 1D data interface) is - point-like.

QCustomPlot holds an ordered list of - one or more instances of QCPLayer (see QCustomPlot::addLayer, QCustomPlot::layer, - QCustomPlot::moveLayer, etc.). When replotting, QCustomPlot goes through the list of layers - bottom to top and successively draws the layerables of the layers into the paint buffer(s). - - A QCPLayer contains an ordered list of QCPLayerable instances. QCPLayerable is an abstract base - class from which almost all visible objects derive, like axes, grids, graphs, items, etc. - - \section qcplayer-defaultlayers Default layers - - Initially, QCustomPlot has six layers: "background", "grid", "main", "axes", "legend" and - "overlay" (in that order). On top is the "overlay" layer, which only contains the QCustomPlot's - selection rect (\ref QCustomPlot::selectionRect). The next two layers "axes" and "legend" contain - the default axes and legend, so they will be drawn above plottables. In the middle, there is the - "main" layer. It is initially empty and set as the current layer (see - QCustomPlot::setCurrentLayer). This means, all new plottables, items etc. are created on this - layer by default. Then comes the "grid" layer which contains the QCPGrid instances (which belong - tightly to QCPAxis, see \ref QCPAxis::grid). The Axis rect background shall be drawn behind - everything else, thus the default QCPAxisRect instance is placed on the "background" layer. Of - course, the layer affiliation of the individual objects can be changed as required (\ref - QCPLayerable::setLayer). - - \section qcplayer-ordering Controlling the rendering order via layers - - Controlling the ordering of layerables in the plot is easy: Create a new layer in the position - you want the layerable to be in, e.g. above "main", with \ref QCustomPlot::addLayer. Then set the - current layer with \ref QCustomPlot::setCurrentLayer to that new layer and finally create the - objects normally. They will be placed on the new layer automatically, due to the current layer - setting. Alternatively you could have also ignored the current layer setting and just moved the - objects with \ref QCPLayerable::setLayer to the desired layer after creating them. - - It is also possible to move whole layers. For example, If you want the grid to be shown in front - of all plottables/items on the "main" layer, just move it above "main" with - QCustomPlot::moveLayer. - - The rendering order within one layer is simply by order of creation or insertion. The item - created last (or added last to the layer), is drawn on top of all other objects on that layer. - - When a layer is deleted, the objects on it are not deleted with it, but fall on the layer below - the deleted layer, see QCustomPlot::removeLayer. - - \section qcplayer-buffering Replotting only a specific layer - - If the layer mode (\ref setMode) is set to \ref lmBuffered, you can replot only this specific - layer by calling \ref replot. In certain situations this can provide better replot performance, - compared with a full replot of all layers. Upon creation of a new layer, the layer mode is - initialized to \ref lmLogical.

The - number of ticks that should be approximately generated can be set via \ref setTickCount. - Depending on the current tick step strategy (\ref setTickStepStrategy), the algorithm either - sacrifices readability to better match the specified tick count (\ref - QCPAxisTicker::tssMeetTickCount) or relaxes the tick count in favor of better tick steps (\ref - QCPAxisTicker::tssReadability), which is the default. - - The following more specialized axis ticker subclasses are available, see details in the - respective class documentation: - -

- - \section axisticker-subclassing Creating own axis tickers - - Creating own axis tickers can be achieved very easily by sublassing QCPAxisTicker and - reimplementing some or all of the available virtual methods. - - In the simplest case you might wish to just generate different tick steps than the other tickers, - so you only reimplement the method \ref getTickStep. If you additionally want control over the - string that will be shown as tick label, reimplement \ref getTickLabel. - - If you wish to have complete control, you can generate the tick vectors and tick label vectors - yourself by reimplementing \ref createTickVector and \ref createLabelVector. The default - implementations use the previously mentioned virtual methods \ref getTickStep and \ref - getTickLabel, but your reimplementations don't necessarily need to do so. For example in the case - of unequal tick steps, the method \ref getTickStep loses its usefulness and can be ignored. - - The sub tick count between major ticks can be controlled with \ref getSubTickCount. Full sub tick - placement control is obtained by reimplementing \ref createSubTickVector. - - See the documentation of all these virtual methods in QCPAxisTicker for detailed information - about the parameters and expected return values. -*/ - -/*! - Constructs the ticker and sets reasonable default values.

The - plot axis coordinate is interpreted as Unix Time, so seconds since Epoch (January 1, 1970, 00:00 - UTC). This is also used for example by QDateTime in the toTime_t()/setTime_t() methods - with a precision of one second. Since Qt 4.7, millisecond accuracy can be obtained from QDateTime - by using QDateTime::fromMSecsSinceEpoch()/1000.0. The static methods \ref dateTimeToKey - and \ref keyToDateTime conveniently perform this conversion achieving a precision of one - millisecond on all Qt versions. - - The format of the date/time display in the tick labels is controlled with \ref setDateTimeFormat. - If a different time spec or time zone shall be used for the tick label appearance, see \ref - setDateTimeSpec or \ref setTimeZone, respectively. - - This ticker produces unequal tick spacing in order to provide intuitive date and time-of-day - ticks. For example, if the axis range spans a few years such that there is one tick per year, - ticks will be positioned on 1. January of every year. This is intuitive but, due to leap years, - will result in slightly unequal tick intervals (visually unnoticeable). The same can be seen in - the image above: even though the number of days varies month by month, this ticker generates - ticks on the same day of each month. - - If you would like to change the date/time that is used as a (mathematical) starting date for the - ticks, use the \ref setTickOrigin(const QDateTime &origin) method overload, which takes a - QDateTime. If you pass 15. July, 9:45 to this method, the yearly ticks will end up on 15. July at - 9:45 of every year. - - The ticker can be created and assigned to an axis like this: - \snippet documentation/doc-image-generator/mainwindow.cpp axistickerdatetime-creation - - \note If you rather wish to display relative times in terms of days, hours, minutes, seconds and - milliseconds, and are not interested in the intricacies of real calendar dates with months and - (leap) years, have a look at QCPAxisTickerTime instead. -*/ - -/*! - Constructs the ticker and sets reasonable default values.

\c yyThe year as a two digit number (00 to 99)
\c yyyyThe year as a four digit number. If the year is negative, a minus sign is prepended, making five characters.
\c hThe hour without a leading zero (0 to 23 or 1 to 12 if AM/PM display)
\c hhThe hour with a leading zero (00 to 23 or 01 to 12 if AM/PM display)
\c HThe hour without a leading zero (0 to 23, even with AM/PM display)

This \a formatCode is an extended version - of the format code used e.g. by QString::number() and QLocale::toString(). For reference about - that, see the "Argument Formats" section in the detailed description of the QString class. - - \a formatCode is a string of one, two or three characters. - - The first character is identical to - the normal format code used by Qt. In short, this means: 'e'/'E' scientific format, 'f' fixed - format, 'g'/'G' scientific or fixed, whichever is shorter. For the 'e', 'E', and 'f' formats, - the precision set by \ref setNumberPrecision represents the number of digits after the decimal - point. For the 'g' and 'G' formats, the precision represents the maximum number of significant - digits, trailing zeroes are omitted. - - The second and third characters are optional and specific to QCustomPlot:\n - If the first char was 'e' or 'g', numbers are/might be displayed in the scientific format, e.g. - "5.5e9", which is ugly in a plot. So when the second char of \a formatCode is set to 'b' (for - "beautiful"), those exponential numbers are formatted in a more natural way, i.e. "5.5 - [multiplication sign] 10 [superscript] 9". By default, the multiplication sign is a centered dot. - If instead a cross should be shown (as is usual in the USA), the third char of \a formatCode can - be set to 'c'. The inserted multiplication signs are the UTF-8 characters 215 (0xD7) for the - cross and 183 (0xB7) for the dot. - - Examples for \a formatCode: - \li \c g normal format code behaviour. If number is small, fixed format is used, if number is large, - normal scientific format is used - \li \c gb If number is small, fixed format is used, if number is large, scientific format is used with - beautifully typeset decimal powers and a dot as multiplication sign - \li \c ebc All numbers are in scientific format with beautifully typeset decimal power and a cross as - multiplication sign - \li \c fb illegal format code, since fixed format doesn't support (or need) beautifully typeset decimal - powers. Format code will be reduced to 'f'. - \li \c hello illegal format code, since first char is not 'e', 'E', 'f', 'g' or 'G'.

In plottables like - QCPGraph it is used to store how scatter points shall be drawn. For example, \ref - QCPGraph::setScatterStyle takes a QCPScatterStyle instance. - - A scatter style consists of a shape (\ref setShape), a line color (\ref setPen) and possibly a - fill (\ref setBrush), if the shape provides a fillable area. Further, the size of the shape can - be controlled with \ref setSize. - - \section QCPScatterStyle-defining Specifying a scatter style - - You can set all these configurations either by calling the respective functions on an instance: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-1 - - Or you can use one of the various constructors that take different parameter combinations, making - it easy to specify a scatter style in a single call, like so: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-2 - - \section QCPScatterStyle-undefinedpen Leaving the color/pen up to the plottable - - There are two constructors which leave the pen undefined: \ref QCPScatterStyle() and \ref - QCPScatterStyle(ScatterShape shape, double size). If those constructors are used, a call to \ref - isPenDefined will return false. It leads to scatter points that inherit the pen from the - plottable that uses the scatter style. Thus, if such a scatter style is passed to QCPGraph, the line - color of the graph (\ref QCPGraph::setPen) will be used by the scatter points. This makes - it very convenient to set up typical scatter settings: - - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-shortcreation - - Notice that it wasn't even necessary to explicitly call a QCPScatterStyle constructor. This works - because QCPScatterStyle provides a constructor that can transform a \ref ScatterShape directly - into a QCPScatterStyle instance (that's the \ref QCPScatterStyle(ScatterShape shape, double size) - constructor with a default for \a size). In those cases, C++ allows directly supplying a \ref - ScatterShape, where actually a QCPScatterStyle is expected. - - \section QCPScatterStyle-custompath-and-pixmap Custom shapes and pixmaps - - QCPScatterStyle supports drawing custom shapes and arbitrary pixmaps as scatter points. - - For custom shapes, you can provide a QPainterPath with the desired shape to the \ref - setCustomPath function or call the constructor that takes a painter path. The scatter shape will - automatically be set to \ref ssCustom. - - For pixmaps, you call \ref setPixmap with the desired QPixmap. Alternatively you can use the - constructor that takes a QPixmap. The scatter shape will automatically be set to \ref ssPixmap. - Note that \ref setSize does not influence the appearance of the pixmap. -*/ - -/* start documentation of inline functions */ - -/*! \fn bool QCPScatterStyle::isNone() const - - Returns whether the scatter shape is \ref ssNone. - - \see setShape -*/ - -/*! \fn bool QCPScatterStyle::isPenDefined() const - - Returns whether a pen has been defined for this scatter style. - - The pen is undefined if a constructor is called that does not carry \a pen as parameter.

If you are worried about performance (i.e. you need - to translate many points in a loop like QCPGraph), you can directly use \ref - QCPAxis::coordToPixel.

QCustomPlot *\b mParentPlotA pointer to the parent QCustomPlot instance. The parent plot is inferred from the axes that are passed in the constructor.
QString \b mNameThe name of the plottable.
QPen \b mPenThe generic pen of the plottable. You should use this pen for the most prominent data representing lines in the plottable - (e.g QCPGraph uses this pen for its graph lines and scatters)
QBrush \b mBrushThe generic brush of the plottable. You should use this brush for the most prominent fillable structures in the plottable - (e.g. QCPGraph uses this brush to control filling under the graph)
QPointer<\ref QCPAxis> \b mKeyAxis, \b mValueAxisThe key and value axes this plottable is attached to. Call their QCPAxis::coordToPixel functions to translate coordinates - to pixels in either the key or value dimension. Make sure to check whether the pointer is \c nullptr before using it. If one of - the axes is null, don't draw the plottable.
\ref QCPSelectionDecorator \b mSelectionDecoratorThe currently set selection decorator which specifies how selected data of the plottable shall be drawn and decorated. - When drawing your data, you must consult this decorator for the appropriate pen/brush before drawing unselected/selected data segments. - Finally, you should call its \ref QCPSelectionDecorator::drawDecoration method at the end of your \ref draw implementation.
\ref QCP::SelectionType \b mSelectableIn which composition, if at all, this plottable's data may be selected. Enforcing this setting on the data selection is done - by QCPAbstractPlottable automatically.

Some items have multiple positions, for example QCPItemRect has two: - \a topLeft and \a bottomRight. - - QCPItemPosition has a type (\ref PositionType) that can be set with \ref setType. This type - defines how coordinates passed to \ref setCoords are to be interpreted, e.g. as absolute pixel - coordinates, as plot coordinates of certain axes (\ref QCPItemPosition::setAxes), as fractions of - the axis rect (\ref QCPItemPosition::setAxisRect), etc. For more advanced plots it is also - possible to assign different types per X/Y coordinate of the position (see \ref setTypeX, \ref - setTypeY). This way an item could be positioned for example at a fixed pixel distance from the - top in the Y direction, while following a plot coordinate in the X direction. - - A QCPItemPosition may have a parent QCPItemAnchor, see \ref setParentAnchor. This way you can tie - multiple items together. If the QCPItemPosition has a parent, its coordinates (\ref setCoords) - are considered to be absolute pixels in the reference frame of the parent anchor, where (0, 0) - means directly ontop of the parent anchor. For example, You could attach the \a start position of - a QCPItemLine to the \a bottom anchor of a QCPItemText to make the starting point of the line - always be centered under the text label, no matter where the text is moved to. For more advanced - plots, it is possible to assign different parent anchors per X/Y coordinate of the position, see - \ref setParentAnchorX, \ref setParentAnchorY. This way an item could follow another item in the X - direction but stay at a fixed position in the Y direction. Or even follow item A in X, and item B - in Y. - - Note that every QCPItemPosition inherits from QCPItemAnchor and thus can itself be used as parent - anchor for other positions. - - To set the apparent pixel position on the QCustomPlot surface directly, use \ref setPixelPosition.

While plottables are always tied to two axes and thus - plot coordinates, items can also be placed in absolute coordinates independent of any axes. Each - specific item has at least one QCPItemPosition member which controls the positioning. Some items - are defined by more than one coordinate and thus have two or more QCPItemPosition members (For - example, QCPItemRect has \a topLeft and \a bottomRight). - - This abstract base class defines a very basic interface like visibility and clipping. Since this - class is abstract, it can't be instantiated. Use one of the subclasses or create a subclass - yourself to create new items. - - The built-in items are: - - - - - - - - - - -
QCPItemLineA line defined by a start and an end point. May have different ending styles on each side (e.g. arrows).
QCPItemStraightLineA straight line defined by a start and a direction point. Unlike QCPItemLine, the straight line is infinitely long and has no endings.
QCPItemCurveA curve defined by start, end and two intermediate control points. May have different ending styles on each side (e.g. arrows).
QCPItemRectA rectangle
QCPItemEllipseAn ellipse
QCPItemPixmapAn arbitrary pixmap
QCPItemTextA text label
QCPItemBracketA bracket which may be used to reference/highlight certain parts in the plot.
QCPItemTracerAn item that can be attached to a QCPGraph and sticks to its data points, given a key coordinate.
- - \section items-clipping Clipping - - Items are by default clipped to the main axis rect (they are only visible inside the axis rect). - To make an item visible outside that axis rect, disable clipping via \ref setClipToAxisRect - "setClipToAxisRect(false)". - - On the other hand if you want the item to be clipped to a different axis rect, specify it via - \ref setClipAxisRect. This clipAxisRect property of an item is only used for clipping behaviour, and - in principle is independent of the coordinate axes the item might be tied to via its position - members (\ref QCPItemPosition::setAxes). However, it is common that the axis rect for clipping - also contains the axes used for the item positions. - - \section items-using Using items - - First you instantiate the item you want to use and add it to the plot: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-1 - by default, the positions of the item are bound to the x- and y-Axis of the plot. So we can just - set the plot coordinates where the line should start/end: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-2 - If we don't want the line to be positioned in plot coordinates but a different coordinate system, - e.g. absolute pixel positions on the QCustomPlot surface, we need to change the position type like this: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-3 - Then we can set the coordinates, this time in pixels: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-4 - and make the line visible on the entire QCustomPlot, by disabling clipping to the axis rect: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-5 - - For more advanced plots, it is even possible to set different types and parent anchors per X/Y - coordinate of an item position, using for example \ref QCPItemPosition::setTypeX or \ref - QCPItemPosition::setParentAnchorX. For details, see the documentation of \ref QCPItemPosition. - - \section items-subclassing Creating own items - - To create an own item, you implement a subclass of QCPAbstractItem. These are the pure - virtual functions, you must implement: - \li \ref selectTest - \li \ref draw - - See the documentation of those functions for what they need to do. - - \subsection items-positioning Allowing the item to be positioned - - As mentioned, item positions are represented by QCPItemPosition members. Let's assume the new item shall - have only one point as its position (as opposed to two like a rect or multiple like a polygon). You then add - a public member of type QCPItemPosition like so: - - \code QCPItemPosition * const myPosition;\endcode - - the const makes sure the pointer itself can't be modified from the user of your new item (the QCPItemPosition - instance it points to, can be modified, of course). - The initialization of this pointer is made easy with the \ref createPosition function. Just assign - the return value of this function to each QCPItemPosition in the constructor of your item. \ref createPosition - takes a string which is the name of the position, typically this is identical to the variable name. - For example, the constructor of QCPItemExample could look like this: - - \code - QCPItemExample::QCPItemExample(QCustomPlot *parentPlot) : - QCPAbstractItem(parentPlot), - myPosition(createPosition("myPosition")) - { - // other constructor code - } - \endcode - - \subsection items-drawing The draw function - - To give your item a visual representation, reimplement the \ref draw function and use the passed - QCPPainter to draw the item. You can retrieve the item position in pixel coordinates from the - position member(s) via \ref QCPItemPosition::pixelPosition. - - To optimize performance you should calculate a bounding rect first (don't forget to take the pen - width into account), check whether it intersects the \ref clipRect, and only draw the item at all - if this is the case. - - \subsection items-selection The selectTest function - - Your implementation of the \ref selectTest function may use the helpers \ref - QCPVector2D::distanceSquaredToLine and \ref rectDistance. With these, the implementation of the - selection test becomes significantly simpler for most items. See the documentation of \ref - selectTest for what the function parameters mean and what the function should return. - - \subsection anchors Providing anchors - - Providing anchors (QCPItemAnchor) starts off like adding a position. First you create a public - member, e.g. - - \code QCPItemAnchor * const bottom;\endcode - - and create it in the constructor with the \ref createAnchor function, assigning it a name and an - anchor id (an integer enumerating all anchors on the item, you may create an own enum for this). - Since anchors can be placed anywhere, relative to the item's position(s), your item needs to - provide the position of every anchor with the reimplementation of the \ref anchorPixelPosition(int - anchorId) function. - - In essence the QCPItemAnchor is merely an intermediary that itself asks your item for the pixel - position when anything attached to the anchor needs to know the coordinates. -*/ - -/* start of documentation of inline functions */ - -/*! \fn QList QCPAbstractItem::positions() const - - Returns all positions of the item in a list. - - \see anchors, position -*/ - -/*! \fn QList QCPAbstractItem::anchors() const - - Returns all anchors of the item in a list.

However, the - layout system allows to have multiple axis rects, e.g. arranged in a grid layout - (QCustomPlot::plotLayout). - - By default, QCPAxisRect comes with four axes, at bottom, top, left and right. They can be - accessed via \ref axis by providing the respective axis type (\ref QCPAxis::AxisType) and index. - If you need all axes in the axis rect, use \ref axes. The top and right axes are set to be - invisible initially (QCPAxis::setVisible). To add more axes to a side, use \ref addAxis or \ref - addAxes. To remove an axis, use \ref removeAxis. - - The axis rect layerable itself only draws a background pixmap or color, if specified (\ref - setBackground). It is placed on the "background" layer initially (see \ref QCPLayer for an - explanation of the QCustomPlot layer system). The axes that are held by the axis rect can be - placed on other layers, independently of the axis rect. - - Every axis rect has a child layout of type \ref QCPLayoutInset. It is accessible via \ref - insetLayout and can be used to have other layout elements (or even other layouts with multiple - elements) hovering inside the axis rect. - - If an axis rect is clicked and dragged, it processes this by moving certain axis ranges. The - behaviour can be controlled with \ref setRangeDrag and \ref setRangeDragAxes. If the mouse wheel - is scrolled while the cursor is on the axis rect, certain axes are scaled. This is controllable - via \ref setRangeZoom, \ref setRangeZoomAxes and \ref setRangeZoomFactor. These interactions are - only enabled if \ref QCustomPlot::setInteractions contains \ref QCP::iRangeDrag and \ref - QCP::iRangeZoom. - - \image html AxisRectSpacingOverview.png -

In the case of the main legend (\ref - QCustomPlot::legend), simply adding plottables to the plot while \ref - QCustomPlot::setAutoAddPlottableToLegend is set to true (the default) creates corresponding - legend items. The legend item associated with a certain plottable can be removed with \ref - QCPAbstractPlottable::removeFromLegend. However, QCPLegend also offers an interface to add and - manipulate legend items directly: \ref item, \ref itemWithPlottable, \ref itemCount, \ref - addItem, \ref removeItem, etc. - - Since \ref QCPLegend derives from \ref QCPLayoutGrid, it can be placed in any position a \ref - QCPLayoutElement may be positioned. The legend items are themselves \ref QCPLayoutElement - "QCPLayoutElements" which are placed in the grid layout of the legend. \ref QCPLegend only adds - an interface specialized for handling child elements of type \ref QCPAbstractLegendItem, as - mentioned above. In principle, any other layout elements may also be added to a legend via the - normal \ref QCPLayoutGrid interface. See the special page about \link thelayoutsystem The Layout - System\endlink for examples on how to add other elements to the legend and move it outside the axis - rect. - - Use the methods \ref setFillOrder and \ref setWrap inherited from \ref QCPLayoutGrid to control - in which order (column first or row first) the legend is filled up when calling \ref addItem, and - at which column or row wrapping occurs. The default fill order for legends is \ref foRowsFirst. - - By default, every QCustomPlot has one legend (\ref QCustomPlot::legend) which is placed in the - inset layout of the main axis rect (\ref QCPAxisRect::insetLayout). To move the legend to another - position inside the axis rect, use the methods of the \ref QCPLayoutInset. To move the legend - outside of the axis rect, place it anywhere else with the \ref QCPLayout/\ref QCPLayoutElement - interface. -*/ - -/* start of documentation of signals */ - -/*! \fn void QCPLegend::selectionChanged(QCPLegend::SelectableParts selection); - - This signal is emitted when the selection state of this legend has changed. - - \see setSelectedParts, setSelectableParts -*/ - -/* end of documentation of signals */ - -/*! - Constructs a new QCPLegend instance with default values. - - Note that by default, QCustomPlot already contains a legend ready to be used as \ref - QCustomPlot::legend -*/ -QCPLegend::QCPLegend() : - mIconTextPadding{} -{ - setFillOrder(QCPLayoutGrid::foRowsFirst); - setWrap(0); - - setRowSpacing(3); - setColumnSpacing(8); - setMargins(QMargins(7, 5, 7, 4)); - setAntialiased(false); - setIconSize(32, 18); - - setIconTextPadding(7); - - setSelectableParts(spLegendBox | spItems); - setSelectedParts(spNone); - - setBorderPen(QPen(Qt::black, 0)); - setSelectedBorderPen(QPen(Qt::blue, 2)); - setIconBorderPen(Qt::NoPen); - setSelectedIconBorderPen(QPen(Qt::blue, 2)); - setBrush(Qt::white); - setSelectedBrush(Qt::white); - setTextColor(Qt::black); - setSelectedTextColor(Qt::blue); -} - -QCPLegend::~QCPLegend() -{ - clearItems(); - if (qobject_cast(mParentPlot)) // make sure this isn't called from QObject dtor when QCustomPlot is already destructed (happens when the legend is not in any layout and thus QObject-child of QCustomPlot) - mParentPlot->legendRemoved(this); -} - -/* no doc for getter, see setSelectedParts */ -QCPLegend::SelectableParts QCPLegend::selectedParts() const -{ - // check whether any legend elements selected, if yes, add spItems to return value - bool hasSelectedItems = false; - for (int i=0; iselected()) - { - hasSelectedItems = true; - break; - } - } - if (hasSelectedItems) - return mSelectedParts | spItems; - else - return mSelectedParts & ~spItems; -} - -/*! - Sets the pen, the border of the entire legend is drawn with. -*/ -void QCPLegend::setBorderPen(const QPen &pen) -{ - mBorderPen = pen; -} - -/*! - Sets the brush of the legend background. -*/ -void QCPLegend::setBrush(const QBrush &brush) -{ - mBrush = brush; -} - -/*! - Sets the default font of legend text.

It - is usually used in combination with one or multiple \ref QCPColorMap "QCPColorMaps". - - \image html QCPColorScale.png - - The color scale can be either horizontal or vertical, as shown in the image above. The - orientation and the side where the numbers appear is controlled with \ref setType. - - Use \ref QCPColorMap::setColorScale to connect a color map with a color scale. Once they are - connected, they share their gradient, data range and data scale type (\ref setGradient, \ref - setDataRange, \ref setDataScaleType). Multiple color maps may be associated with a single color - scale, to make them all synchronize these properties. - - To have finer control over the number display and axis behaviour, you can directly access the - \ref axis. See the documentation of QCPAxis for details about configuring axes. For example, if - you want to change the number of automatically generated ticks, call - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-tickcount - - Placing a color scale next to the main axis rect works like with any other layout element: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-creation - In this case we have placed it to the right of the default axis rect, so it wasn't necessary to - call \ref setType, since \ref QCPAxis::atRight is already the default. The text next to the color - scale can be set with \ref setLabel. - - For optimum appearance (like in the image above), it may be desirable to line up the axis rect and - the borders of the color scale. Use a \ref QCPMarginGroup to achieve this: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-margingroup - - Color scales are initialized with a non-zero minimum top and bottom margin (\ref - setMinimumMargins), because vertical color scales are most common and the minimum top/bottom - margin makes sure it keeps some distance to the top/bottom widget border. So if you change to a - horizontal color scale by setting \ref setType to \ref QCPAxis::atBottom or \ref QCPAxis::atTop, you - might want to also change the minimum margins accordingly, e.g. setMinimumMargins(QMargins(6, 0, 6, 0)). -*/ - -/* start documentation of inline functions */ - -/*! \fn QCPAxis *QCPColorScale::axis() const - - Returns the internal \ref QCPAxis instance of this color scale.

It holds a two-dimensional array, which \ref - QCPColorMap then displays as a 2D image in the plot, where the array values are represented by a - color, depending on the value. - - The size of the array can be controlled via \ref setSize (or \ref setKeySize, \ref setValueSize). - Which plot coordinates these cells correspond to can be configured with \ref setRange (or \ref - setKeyRange, \ref setValueRange). - - The data cells can be accessed in two ways: They can be directly addressed by an integer index - with \ref setCell. This is the fastest method. Alternatively, they can be addressed by their plot - coordinate with \ref setData. plot coordinate to cell index transformations and vice versa are - provided by the functions \ref coordToCell and \ref cellToCoord. - - A \ref QCPColorMapData also holds an on-demand two-dimensional array of alpha values which (if - allocated) has the same size as the data map. It can be accessed via \ref setAlpha, \ref - fillAlpha and \ref clearAlpha. The memory for the alpha map is only allocated if needed, i.e. on - the first call of \ref setAlpha. \ref clearAlpha restores full opacity and frees the alpha map. - - This class also buffers the minimum and maximum values that are in the data set, to provide - QCPColorMap::rescaleDataRange with the necessary information quickly. Setting a cell to a value - that is greater than the current maximum increases this maximum to the new value. However, - setting the cell that currently holds the maximum value to a smaller value doesn't decrease the - maximum again, because finding the true new maximum would require going through the entire data - array, which might be time consuming. The same holds for the data minimum. This functionality is - given by \ref recalculateDataBounds, such that you can decide when it is sensible to find the - true current minimum and maximum.

As with other plottables such as graphs, \a key and \a value - correspond to two orthogonal axes on the QCustomPlot surface that you specify in the QCPColorMap - constructor. The \a data dimension however is encoded as the color of the point at (\a key, \a - value). - - Set the number of points (or \a cells) in the key/value dimension via \ref - QCPColorMapData::setSize. The plot coordinate range over which these points will be displayed is - specified via \ref QCPColorMapData::setRange. The first cell will be centered on the lower range - boundary and the last cell will be centered on the upper range boundary. The data can be set by - either accessing the cells directly with QCPColorMapData::setCell or by addressing the cells via - their plot coordinates with \ref QCPColorMapData::setData. If possible, you should prefer - setCell, since it doesn't need to do any coordinate transformation and thus performs a bit - better. - - The cell with index (0, 0) is at the bottom left, if the color map uses normal (i.e. not reversed) - key and value axes. - - To show the user which colors correspond to which \a data values, a \ref QCPColorScale is - typically placed to the right of the axis rect. See the documentation there for details on how to - add and use a color scale. - - \section qcpcolormap-appearance Changing the appearance - - Most important to the appearance is the color gradient, which can be specified via \ref - setGradient. See the documentation of \ref QCPColorGradient for details on configuring a color - gradient. - - The \a data range that is mapped to the colors of the gradient can be specified with \ref - setDataRange. To make the data range encompass the whole data set minimum to maximum, call \ref - rescaleDataRange. If your data may contain NaN values, use \ref QCPColorGradient::setNanHandling - to define how they are displayed. - - \section qcpcolormap-transparency Transparency - - Transparency in color maps can be achieved by two mechanisms. On one hand, you can specify alpha - values for color stops of the \ref QCPColorGradient, via the regular QColor interface. This will - cause the color map data which gets mapped to colors around those color stops to appear with the - accordingly interpolated transparency. - - On the other hand you can also directly apply an alpha value to each cell independent of its - data, by using the alpha map feature of \ref QCPColorMapData. The relevant methods are \ref - QCPColorMapData::setAlpha, QCPColorMapData::fillAlpha and \ref QCPColorMapData::clearAlpha(). - - The two transparencies will be joined together in the plot and otherwise not interfere with each - other. They are mixed in a multiplicative matter, so an alpha of e.g. 50% (128/255) in both modes - simultaneously, will result in a total transparency of 25% (64/255). - - \section qcpcolormap-usage Usage - - Like all data representing objects in QCustomPlot, the QCPColorMap is a plottable - (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies - (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.) - - Usually, you first create an instance: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-1 - which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes - ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead. - The newly created plottable can be modified, e.g.: - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-2 - - \note The QCPColorMap always displays the data at equal key/value intervals, even if the key or - value axis is set to a logarithmic scaling. If you want to use QCPColorMap with logarithmic axes, - you shouldn't use the \ref QCPColorMapData::setData method as it uses a linear transformation to - determine the cell index.

The two common representations OHLC (Open-High-Low-Close) bars and Candlesticks can be - set via \ref setChartStyle. - - The data is passed via \ref setData as a set of open/high/low/close values at certain keys - (typically times). This means the data must be already binned appropriately. If data is only - available as a series of values (e.g. \a price against \a time), you can use the static - convenience function \ref timeSeriesToOhlc to generate binned OHLC-data which can then be passed - to \ref setData. - - The width of the OHLC bars/candlesticks can be controlled with \ref setWidth and \ref - setWidthType. A typical choice is to set the width type to \ref wtPlotCoords (the default) and - the width to (or slightly less than) one time bin interval width. - - \section qcpfinancial-appearance Changing the appearance - - Charts can be either single- or two-colored (\ref setTwoColored). If set to be single-colored, - lines are drawn with the plottable's pen (\ref setPen) and fills with the brush (\ref setBrush). - - If set to two-colored, positive changes of the value during an interval (\a close >= \a open) are - represented with a different pen and brush than negative changes (\a close < \a open). These can - be configured with \ref setPenPositive, \ref setPenNegative, \ref setBrushPositive, and \ref - setBrushNegative. In two-colored mode, the normal plottable pen/brush is ignored. Upon selection - however, the normal selected pen/brush (provided by the \ref selectionDecorator) is used, - irrespective of whether the chart is single- or two-colored. - - \section qcpfinancial-usage Usage - - Like all data representing objects in QCustomPlot, the QCPFinancial is a plottable - (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies - (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.) - - Usually, you first create an instance: - - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-1 - which registers it with the QCustomPlot instance of the passed axes.

The newly created plottable can be modified, e.g.: - - \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-2 - Here we have used the static helper method \ref timeSeriesToOhlc, to turn a time-price data - series into a 24-hour binned open-high-low-close data series as QCPFinancial uses. -*/ - -/* start of documentation of inline functions */ - -/*! \fn QCPFinancialDataContainer *QCPFinancial::data() const - - Returns a pointer to the internal data storage of type \ref QCPFinancialDataContainer.

\class QCPDataContainer - \brief The generic data container for one-dimensional plottables - - This class template provides a fast container for data storage of one-dimensional data. The data - type is specified as template parameter (called \a DataType in the following) and must provide - some methods as described in the \ref qcpdatacontainer-datatype "next section". - - The data is stored in a sorted fashion, which allows very quick lookups by the sorted key as well - as retrieval of ranges (see \ref findBegin, \ref findEnd, \ref keyRange) using binary search. The - container uses a preallocation and a postallocation scheme, such that appending and prepending - data (with respect to the sort key) is very fast and minimizes reallocations. If data is added - which needs to be inserted between existing keys, the merge usually can be done quickly too, - using the fact that existing data is always sorted. The user can further improve performance by - specifying that added data is already itself sorted by key, if he can guarantee that this is the - case (see for example \ref add(const QVector &data, bool alreadySorted)). - - The data can be accessed with the provided const iterators (\ref constBegin, \ref constEnd). If - it is necessary to alter existing data in-place, the non-const iterators can be used (\ref begin, - \ref end). Changing data members that are not the sort key (for most data types called \a key) is - safe from the container's perspective. - - Great care must be taken however if the sort key is modified through the non-const iterators. For - performance reasons, the iterators don't automatically cause a re-sorting upon their - manipulation. It is thus the responsibility of the user to leave the container in a sorted state - when finished with the data manipulation, before calling any other methods on the container. A - complete re-sort (e.g. after finishing all sort key manipulation) can be done by calling \ref - sort. Failing to do so can not be detected by the container efficiently and will cause both - rendering artifacts and potential data loss. - - Implementing one-dimensional plottables that make use of a \ref QCPDataContainer is usually - done by subclassing from \ref QCPAbstractPlottable1D "QCPAbstractPlottable1D", which - introduces an according \a mDataContainer member and some convenience methods. - - \section qcpdatacontainer-datatype Requirements for the DataType template parameter - - The template parameter DataType is the type of the stored data points. It must be - trivially copyable and have the following public methods, preferably inline: - - \li double sortKey() const\n Returns the member variable of this data point that is the - sort key, defining the ordering in the container. Often this variable is simply called \a key. - - \li static DataType fromSortKey(double sortKey)\n Returns a new instance of the data - type initialized with its sort key set to \a sortKey. - - \li static bool sortKeyIsMainKey()\n Returns true if the sort key is equal to the main - key (see method \c mainKey below). For most plottables this is the case. It is not the case for - example for \ref QCPCurve, which uses \a t as sort key and \a key as main key. This is the reason - why QCPCurve unlike QCPGraph can display parametric curves with loops. - - \li double mainKey() const\n Returns the variable of this data point considered the main - key. This is commonly the variable that is used as the coordinate of this data point on the key - axis of the plottable. This method is used for example when determining the automatic axis - rescaling of key axes (\ref QCPAxis::rescale). - - \li double mainValue() const\n Returns the variable of this data point considered the - main value. This is commonly the variable that is used as the coordinate of this data point on - the value axis of the plottable. - - \li QCPRange valueRange() const\n Returns the range this data point spans in the value - axis coordinate. If the data is single-valued (e.g. QCPGraphData), this is simply a range with - both lower and upper set to the main data point value. However if the data points can represent - multiple values at once (e.g QCPFinancialData with its \a high, \a low, \a open and \a close - values at each \a key) this method should return the range those values span. This method is used - for example when determining the automatic axis rescaling of value axes (\ref - QCPAxis::rescale). -*/ - -/* start documentation of inline functions */ - -/*! \fn int QCPDataContainer::size() const - - Returns the number of data points in the container. -*/ - -/*! \fn bool QCPDataContainer::isEmpty() const - - Returns whether this container holds no data points. -*/ - -/*! \fn QCPDataContainer::const_iterator QCPDataContainer::constBegin() const - - Returns a const iterator to the first data point in this container. -*/ - -/*! \fn QCPDataContainer::const_iterator QCPDataContainer::constEnd() const - - Returns a const iterator to the element past the last data point in this container. -*/ - -/*! \fn QCPDataContainer::iterator QCPDataContainer::begin() const - - Returns a non-const iterator to the first data point in this container. - - You can manipulate the data points in-place through the non-const iterators, but great care must - be taken when manipulating the sort key of a data point, see \ref sort, or the detailed - description of this class. -*/ - -/*! \fn QCPDataContainer::iterator QCPDataContainer::end() const - - Returns a non-const iterator to the element past the last data point in this container. - - You can manipulate the data points in-place through the non-const iterators, but great care must - be taken when manipulating the sort key of a data point, see \ref sort, or the detailed - description of this class. -*/ - -/*! \fn QCPDataContainer::const_iterator QCPDataContainer::at(int index) const - - Returns a const iterator to the element with the specified \a index.

It serves as a base class for all one-dimensional data (i.e. data with - one key dimension), such as \ref QCPGraph and QCPCurve. - - The template parameter \a DataType is the type of the data points of this plottable (e.g. \ref - QCPGraphData or \ref QCPCurveData). The main purpose of this base class is to provide the member - \a mDataContainer (a shared pointer to a \ref QCPDataContainer "QCPDataContainer") and - implement the according virtual methods of the \ref QCPPlottableInterface1D, such that most - subclassed plottables don't need to worry about this anymore. - - Further, it provides a convenience method for retrieving selected/unselected data segments via - \ref getDataSegments. This is useful when subclasses implement their \ref draw method and need to - draw selected segments with a different pen/brush than unselected segments (also see \ref - QCPSelectionDecorator). - - This class implements basic functionality of \ref QCPAbstractPlottable::selectTest and \ref - QCPPlottableInterface1D::selectTestRect, assuming point-like data points, based on the 1D data - interface. In spite of that, most plottable subclasses will want to reimplement those methods - again, to provide a more accurate hit test based on their specific data visualization geometry. -*/ - -/* start documentation of inline functions */ - -/*! \fn QCPPlottableInterface1D *QCPAbstractPlottable1D::interface1D() - - Returns a \ref QCPPlottableInterface1D pointer to this plottable, providing access to its 1D - interface. - - \seebaseclassmethod -*/ - -/* end documentation of inline functions */ - -/*! - Forwards \a keyAxis and \a valueAxis to the \ref QCPAbstractPlottable::QCPAbstractPlottable - "QCPAbstractPlottable" constructor and allocates the \a mDataContainer. -*/ -template -QCPAbstractPlottable1D::QCPAbstractPlottable1D(QCPAxis *keyAxis, QCPAxis *valueAxis) : - QCPAbstractPlottable(keyAxis, valueAxis), - mDataContainer(new QCPDataContainer) -{ -} - -template -QCPAbstractPlottable1D::~QCPAbstractPlottable1D() -{ -} - -/*! - \copydoc QCPPlottableInterface1D::dataCount -*/ -template -int QCPAbstractPlottable1D::dataCount() const -{ - return mDataContainer->size(); -} - -/*! - \copydoc QCPPlottableInterface1D::dataMainKey -*/ -template -double QCPAbstractPlottable1D::dataMainKey(int index) const -{ - if (index >= 0 && index < mDataContainer->size()) - { - return (mDataContainer->constBegin()+index)->mainKey(); - } else - { - qDebug() << Q_FUNC_INFO << "Index out of bounds" << index; - return 0; - } -} - -/*! - \copydoc QCPPlottableInterface1D::dataSortKey -*/ -template -double QCPAbstractPlottable1D::dataSortKey(int index) const -{ - if (index >= 0 && index < mDataContainer->size()) - { - return (mDataContainer->constBegin()+index)->sortKey(); - } else - { - qDebug() << Q_FUNC_INFO << "Index out of bounds" << index; - return 0; - } -} - -/*! - \copydoc QCPPlottableInterface1D::dataMainValue -*/ -template -double QCPAbstractPlottable1D::dataMainValue(int index) const -{ - if (index >= 0 && index < mDataContainer->size()) - { - return (mDataContainer->constBegin()+index)->mainValue(); - } else - { - qDebug() << Q_FUNC_INFO << "Index out of bounds" << index; - return 0; - } -} - -/*! - \copydoc QCPPlottableInterface1D::dataValueRange -*/ -template -QCPRange QCPAbstractPlottable1D::dataValueRange(int index) const -{ - if (index >= 0 && index < mDataContainer->size()) - { - return (mDataContainer->constBegin()+index)->valueRange(); - } else - { - qDebug() << Q_FUNC_INFO << "Index out of bounds" << index; - return QCPRange(0, 0); - } -} - -/*! - \copydoc QCPPlottableInterface1D::dataPixelPosition -*/ -template -QPointF QCPAbstractPlottable1D::dataPixelPosition(int index) const -{ - if (index >= 0 && index < mDataContainer->size()) - { - const typename QCPDataContainer::const_iterator it = mDataContainer->constBegin()+index; - return coordsToPixels(it->mainKey(), it->mainValue()); - } else - { - qDebug() << Q_FUNC_INFO << "Index out of bounds" << index; - return QPointF(); - } -} - -/*! - \copydoc QCPPlottableInterface1D::sortKeyIsMainKey -*/ -template -bool QCPAbstractPlottable1D::sortKeyIsMainKey() const -{ - return DataType::sortKeyIsMainKey(); -} - -/*! - Implements a rect-selection algorithm assuming the data (accessed via the 1D data interface) is - point-like.
