◆ RefreshPriority [1/2]

enum QCustomPlot::RefreshPriority

Defines with what timing the QCustomPlot surface is refreshed after a replot.

See also: replot

Enumerator
rpImmediateRefresh	Replots immediately and repaints the widget immediately by calling QWidget::repaint() after the replot
rpQueuedRefresh	Replots immediately, but queues the widget repaint, by calling QWidget::update() after the replot. This way multiple redundant widget repaints can be avoided.
rpRefreshHint	Whether to use immediate or queued refresh depends on whether the plotting hint QCP::phImmediateRefresh is set, see setPlottingHints.
rpQueuedReplot	Queues the entire replot for the next event loop iteration. This way multiple redundant replots can be avoided. The actual replot is then done with rpRefreshHint priority.
rpImmediate	The QCustomPlot surface is immediately refreshed, by calling QWidget::repaint() after the replot
rpQueued	Queues the refresh such that it is performed at a slightly delayed point in time after the replot, by calling QWidget::update() after the replot
rpHint	Whether to use immediate repaint or queued update depends on whether the plotting hint QCP::phForceRepaint is set, see setPlottingHints.

Member Function Documentation

◆ addGraph() [1/2]

QCPGraph * QCustomPlot::addGraph	(	QCPAxis *	keyAxis = `0`,
		QCPAxis *	valueAxis = `0`
	)

Creates a new graph inside the plot. If keyAxis and valueAxis are left unspecified (0), the bottom (xAxis) is used as key and the left (yAxis) is used as value axis. If specified, keyAxis and valueAxis must reside in this QCustomPlot.

keyAxis will be used as key axis (typically "x") and valueAxis as value axis (typically "y") for the graph.

Returns a pointer to the newly created graph, or 0 if adding the graph failed.

See also: graph, graphCount, removeGraph, clearGraphs

		QCPAxis *	valueAxis = `0`
	)

◆ addItem()

bool QCustomPlot::addItem ( QCPAbstractItem * item )

Adds the specified item to the plot. QCustomPlot takes ownership of the item.

Returns true on success, i.e. when item wasn't already in the plot and the parent plot of item is this QCustomPlot.

See also: item, itemCount, removeItem, clearItems

Definition at line 10136 of file qcustomplot.cpp.

References item(), mItems, and QCPLayerable::parentPlot().

◆ addLayer() [1/2]

bool QCustomPlot::addLayer	(	const QString &	name,
		QCPLayer *	otherLayer = `0`,
		QCustomPlot::LayerInsertMode	insertMode = `limAbove`
	)

Adds a new layer to this QCustomPlot instance. The new layer will have the name name, which must be unique. Depending on insertMode, it is positioned either below or above otherLayer.

Returns true on success, i.e. if there is no other layer named name and otherLayer is a valid layer inside this QCustomPlot.

If otherLayer is 0, the highest layer in the QCustomPlot will be used.

For an explanation of what layers are in QCustomPlot, see the documentation of QCPLayer.

		LayerInsertMode	insertMode = `limAbove`
	)

◆ addPlottable()

bool QCustomPlot::addPlottable ( QCPAbstractPlottable * plottable )

Adds the specified plottable to the plot and, if setAutoAddPlottableToLegend is enabled, to the legend (QCustomPlot::legend). QCustomPlot takes ownership of the plottable.

Returns true on success, i.e. when plottable isn't already in the plot and the parent plot of plottable is this QCustomPlot (the latter is controlled by what axes were passed in the plottable's constructor).

◆ afterReplot [1/2]

void QCustomPlot::afterReplot ( )

signal

This signal is emitted immediately after a replot has taken place (caused by a call to the slot replot).

It is safe to mutually connect the replot slot with this signal on two QCustomPlots to make them replot synchronously, it won't cause an infinite recursion.

◆ axisClick [1/2]

void QCustomPlot::axisClick	(	QCPAxis *	axis,
		QCPAxis::SelectablePart	part,
		QMouseEvent *	event
	)

signal

This signal is emitted when an axis is clicked.

event is the mouse event that caused the click, axis is the axis that received the click and part indicates the part of the axis that was clicked.

signal

◆ axisRect() [1/2]

QCPAxisRect * QCustomPlot::axisRect ( int index = 0 ) const

Returns the axis rect with index.

Initially, only one axis rect (with index 0) exists in the plot. If multiple axis rects were added, all of them may be accessed with this function in a linear fashion (even when they are nested in a layout hierarchy or inside other axis rects via QCPAxisRect::insetLayout).

The order of the axis rects is given by the fill order of the QCPLayout that is holding them. For example, if the axis rects are in the top level grid layout (accessible via QCustomPlot::plotLayout), they are ordered from left to right, top to bottom, if the layout's default setFillOrder of foColumnsFirst wasn't changed.

If you want to access axis rects by their row and column index, use the layout interface. For example, use QCPLayoutGrid::element of the top level grid layout, and qobject_cast the returned layout element to QCPAxisRect. (See also thelayoutsystem.)

See also: axisRectCount, axisRects, QCPLayoutGrid::setFillOrder

Returns the axis rect with index.

Initially, only one axis rect (with index 0) exists in the plot. If multiple axis rects were added, all of them may be accessed with this function in a linear fashion (even when they are nested in a layout hierarchy or inside other axis rects via QCPAxisRect::insetLayout).

QCPAxisRect* QCustomPlot::axisRect ( int index = 0 ) const

◆ axisRectAt()

QCPAxisRect * QCustomPlot::axisRectAt ( const QPointF & pos ) const

Returns the layout element of type QCPAxisRect at pixel position pos. This method ignores other layout elements even if they are visually in front of the axis rect (e.g. a QCPLegend). If there is no axis rect at that position, returns 0.

Only visible axis rects are used. If QCPLayoutElement::setVisible on the axis rect itself or on any of its parent elements is set to false, it will not be considered.

Warning: It is discouraged to change the drag-axes with QCPAxisRect::setRangeDragAxes here, because the dragging starting point was saved the moment the mouse was pressed. Thus it only has a meaning for the range drag axes that were set at that moment. If you want to change the drag axes, consider doing this in the mousePress signal instead.

◆ replot() [2/2]

void QCustomPlot::replot ( QCustomPlot::RefreshPriority refreshPriority = QCustomPlot::rpRefreshHint )

Causes a complete replot into the internal paint buffer(s). Finally, the widget surface is refreshed with the new buffer contents. This is the method that must be called to make changes to the plot, e.g. on the axis ranges or data points of graphs, visible.

The parameter refreshPriority can be used to fine-tune the timing of the replot. For example if your application calls replot very quickly in succession (e.g. multiple independent functions change some aspects of the plot and each wants to make sure the change gets replotted), it is advisable to set refreshPriority to QCustomPlot::rpQueuedReplot. This way, the actual replotting is deferred to the next event loop iteration. Multiple successive calls of replot with this priority will only cause a single replot, avoiding redundant replots and improving performance.

Under a few circumstances, QCustomPlot causes a replot by itself. Those are resize events of the QCustomPlot widget and user interactions (object selection and range dragging/zooming).

Before the replot happens, the signal beforeReplot is emitted. After the replot, afterReplot is emitted. It is safe to mutually connect the replot slot with any of those two signals on two QCustomPlots to make them replot synchronously, it won't cause an infinite recursion.

If a layer is in mode QCPLayer::lmBuffered (QCPLayer::setMode), it is also possible to replot only that specific layer via QCPLayer::replot. See the documentation there for details.

Causes a complete replot into the internal buffer. Finally, update() is called, to redraw the buffer on the QCustomPlot widget surface. This is the method that must be called to make changes, for example on the axis ranges or data points of graphs, visible.

bool QCustomPlot::saveBmp	(	const QString &	fileName,
		int	width = `0`,
		int	height = `0`,
		double	scale = `1.0`
	)

Saves a BMP image file to fileName on disc. The output plot will have the dimensions width and height in pixels. If either width or height is zero, the exported image will have the same dimensions as the QCustomPlot widget currently has. Line widths and texts etc. are not scaled up when larger widths/heights are used. If you want that effect, use the scale parameter.

For example, if you set both width and height to 100 and scale to 2, you will end up with an image file of size 200*200 in which all graphical elements are scaled up by factor 2 (line widths, texts, etc.). This scaling is not done by stretching a 100*100 image, the result will have full 200*200 pixel resolution.

If you use a high scaling factor, it is recommended to enable antialiasing for all elements via temporarily setting QCustomPlot::setAntialiasedElements to QCP::aeAll as this allows QCustomPlot to place objects with sub-pixel accuracy.

Warning: If calling this function inside the constructor of the parent of the QCustomPlot widget (i.e. the MainWindow constructor, if QCustomPlot is inside the MainWindow), always provide explicit non-zero widths and heights. If you leave width or height as 0 (default), this function uses the current width and height of the QCustomPlot widget. However, in Qt, these aren't defined yet inside the constructor, so you would get an image that has strange widths/heights.

The objects of the plot will appear in the current selection state. If you don't want any selected objects to be painted in their selected look, deselect everything with deselectAll before calling this function.

Returns true on success. If this function fails, most likely the BMP format isn't supported by the system, see Qt docs about QImageWriter::supportedImageFormats().

Saves a BMP image file to fileName on disc. The output plot will have the dimensions width and height in pixels, multiplied by scale. If either width or height is zero, the current width and height of the QCustomPlot widget is used instead. Line widths and texts etc. are not scaled up when larger widths/heights are used. If you want that effect, use the scale parameter.

For example, if you set both width and height to 100 and scale to 2, you will end up with an image file of size 200*200 in which all graphical elements are scaled up by factor 2 (line widths, texts, etc.).

If you use a high scaling factor, it is recommended to enable antialiasing for all elements by temporarily setting QCustomPlot::setAntialiasedElements to QCP::aeAll as this allows QCustomPlot to place objects with sub-pixel accuracy.

The resolution will be written to the image file header and has no direct consequence for the quality or the pixel size. However, if opening the image with a tool which respects the metadata, it will be able to scale the image to match either a given size in real units of length (inch, centimeters, etc.), or the target display DPI. You can specify in which units resolution is given, by setting resolutionUnit. The resolution is converted to the format's expected resolution unit internally.

Returns true on success. If this function fails, most likely the BMP format isn't supported by the system, see Qt docs about QImageWriter::supportedImageFormats().

		const QString &	pdfTitle = `QString()`
	)

Saves a PDF with the vectorized plot to the file fileName. The axis ratio as well as the scale of texts and lines will be derived from the specified width and height. This means, the output will look like the normal on-screen output of a QCustomPlot widget with the corresponding pixel width and height. If either width or height is zero, the exported image will have the same dimensions as the QCustomPlot widget currently has.

noCosmeticPen disables the use of cosmetic pens when drawing to the PDF file. Cosmetic pens are pens with numerical width 0, which are always drawn as a one pixel wide line, no matter what zoom factor is set in the PDF-Viewer. For more information about cosmetic pens, see the QPainter and QPen documentation.

The objects of the plot will appear in the current selection state. If you don't want any selected objects to be painted in their selected look, deselect everything with deselectAll before calling this function.

Returns true on success.

Warning

If you plan on editing the exported PDF file with a vector graphics editor like Inkscape, it is advised to set noCosmeticPen to true to avoid losing those cosmetic lines (which might be quite many, because cosmetic pens are the default for e.g. axes and tick marks).

◆ savePng() [1/2]

bool QCustomPlot::savePng	(	const QString &	fileName,
		int	width = `0`,
		int	height = `0`,
		double	scale = `1.0`,
		int	quality = `-1`
	)

Saves a PNG image file to fileName on disc. The output plot will have the dimensions width and height in pixels. If either width or height is zero, the exported image will have the same dimensions as the QCustomPlot widget currently has. Line widths and texts etc. are not scaled up when larger widths/heights are used. If you want that effect, use the scale parameter.

For example, if you set both width and height to 100 and scale to 2, you will end up with an image file of size 200*200 in which all graphical elements are scaled up by factor 2 (line widths, texts, etc.). This scaling is not done by stretching a 100*100 image, the result will have full 200*200 pixel resolution.

If you use a high scaling factor, it is recommended to enable antialiasing for all elements via temporarily setting QCustomPlot::setAntialiasedElements to QCP::aeAll as this allows QCustomPlot to place objects with sub-pixel accuracy.

Warning: If calling this function inside the constructor of the parent of the QCustomPlot widget (i.e. the MainWindow constructor, if QCustomPlot is inside the MainWindow), always provide explicit non-zero widths and heights. If you leave width or height as 0 (default), this function uses the current width and height of the QCustomPlot widget. However, in Qt, these aren't defined yet inside the constructor, so you would get an image that has strange widths/heights.

The objects of the plot will appear in the current selection state. If you don't want any selected objects to be painted in their selected look, deselect everything with deselectAll before calling this function.

If you want the PNG to have a transparent background, call setBackground(const QBrush &brush) with no brush (Qt::NoBrush) or a transparent color (Qt::transparent), before saving.

PNG compression can be controlled with the quality parameter which must be between 0 and 100 or -1 to use the default setting.

Returns true on success. If this function fails, most likely the PNG format isn't supported by the system, see Qt docs about QImageWriter::supportedImageFormats().

Saves a PNG image file to fileName on disc. The output plot will have the dimensions width and height in pixels, multiplied by scale. If either width or height is zero, the current width and height of the QCustomPlot widget is used instead. Line widths and texts etc. are not scaled up when larger widths/heights are used. If you want that effect, use the scale parameter.

For example, if you set both width and height to 100 and scale to 2, you will end up with an image file of size 200*200 in which all graphical elements are scaled up by factor 2 (line widths, texts, etc.).

image compression can be controlled with the quality parameter which must be between 0 and 100 or -1 to use the default setting.

The resolution will be written to the image file header and has no direct consequence for the quality or the pixel size. However, if opening the image with a tool which respects the metadata, it will be able to scale the image to match either a given size in real units of length (inch, centimeters, etc.), or the target display DPI. You can specify in which units resolution is given, by setting resolutionUnit. The resolution is converted to the format's expected resolution unit internally.

Returns true on success. If this function fails, most likely the PNG format isn't supported by the system, see Qt docs about QImageWriter::supportedImageFormats().

Saves the plot to a rastered image file fileName in the image format format. The plot is sized to width and height in pixels and scaled with scale.

Sets which elements are forcibly drawn antialiased as an or combination of QCP::AntialiasedElement.

This overrides the antialiasing settings for whole element groups, normally controlled with the setAntialiasing function on the individual elements. If an element is neither specified in setAntialiasedElements nor in setNotAntialiasedElements, the antialiasing setting on each individual element instance is used.

For example, if antialiasedElements contains QCP::aePlottables, all plottables will be drawn antialiased, no matter what the specific QCPAbstractPlottable::setAntialiased value was set to.

if an element in antialiasedElements is already set in setNotAntialiasedElements, it is removed from there.

Before drawing everything else, the background is filled with brush. If a background pixmap was set with setBackground(const QPixmap &pm), this brush will be used to fill the viewport before the background pixmap is drawn. This can be useful for background pixmaps with translucent areas.

Set brush to Qt::NoBrush or Qt::Transparent to leave background transparent. This can be useful for exporting to image formats which support transparency, e.g. savePng.

void QCustomPlot::setBackground ( const QPixmap & pm )

Sets pm as the viewport background pixmap (see setViewport). The pixmap is always drawn below all other objects in the plot.

For cases where the provided pixmap doesn't have the same size as the viewport, scaling can be enabled with setBackgroundScaled and the scaling mode (whether and how the aspect ratio is preserved) can be set with setBackgroundScaledMode. To set all these options in one call, consider using the overloaded version of this function.

If a background brush was set with setBackground(const QBrush &brush), the viewport will first be filled with that brush, before drawing the background pixmap. This can be useful for background pixmaps with translucent areas.

◆ setInteractions() [1/2]

void QCustomPlot::setInteractions ( const QCP::Interactions & interactions )

Sets the possible interactions of this QCustomPlot as an or-combination of QCP::Interaction enums. There are the following types of interactions:

Axis range manipulation is controlled via QCP::iRangeDrag and QCP::iRangeZoom. When the respective interaction is enabled, the user may drag axes ranges and zoom with the mouse wheel. For details how to control which axes the user may drag/zoom and in what orientations, see QCPAxisRect::setRangeDrag, QCPAxisRect::setRangeZoom, QCPAxisRect::setRangeDragAxes, QCPAxisRect::setRangeZoomAxes.

Plottable data selection is controlled by QCP::iSelectPlottables. If QCP::iSelectPlottables is set, the user may select plottables (graphs, curves, bars,...) and their data by clicking on them or in their vicinity (setSelectionTolerance). Whether the user can actually select a plottable and its data can further be restricted with the QCPAbstractPlottable::setSelectable method on the specific plottable. For details, see the special page about the data selectionmechanism". To retrieve a list of all currently selected plottables, call selectedPlottables. If you're only interested in QCPGraphs, you may use the convenience function selectedGraphs.

Item selection is controlled by QCP::iSelectItems. If QCP::iSelectItems is set, the user may select items (QCPItemLine, QCPItemText,...) by clicking on them or in their vicinity. To find out whether a specific item is selected, call QCPAbstractItem::selected(). To retrieve a list of all currently selected items, call selectedItems.

Axis selection is controlled with QCP::iSelectAxes. If QCP::iSelectAxes is set, the user may select parts of the axes by clicking on them. What parts exactly (e.g. Axis base line, tick labels, axis label) are selectable can be controlled via QCPAxis::setSelectableParts for each axis. To retrieve a list of all axes that currently contain selected parts, call selectedAxes. Which parts of an axis are selected, can be retrieved with QCPAxis::selectedParts().

Legend selection is controlled with QCP::iSelectLegend. If this is set, the user may select the legend itself or individual items by clicking on them. What parts exactly are selectable can be controlled via QCPLegend::setSelectableParts. To find out whether the legend or any of its child items are selected, check the value of QCPLegend::selectedParts. To find out which child items are selected, call QCPLegend::selectedItems.

All other selectable elements The selection of all other selectable objects (e.g. QCPTextElement, or your own layerable subclasses) is controlled with QCP::iSelectOther. If set, the user may select those objects by clicking on them. To find out which are currently selected, you need to check their selected state explicitly.

If the selection state has changed by user interaction, the selectionChangedByUser signal is emitted. Each selectable object additionally emits an individual selectionChanged signal whenever their selection state has changed, i.e. not only by user interaction.

To allow multiple objects to be selected by holding the selection modifier (setMultiSelectModifier), set the flag QCP::iMultiSelect.

Note: In addition to the selection mechanism presented here, QCustomPlot always emits corresponding signals, when an object is clicked or double clicked. see plottableClick and plottableDoubleClick for example.

See also: setInteraction, setSelectionTolerance

Sets the possible interactions of this QCustomPlot as an or-combination of QCP::Interaction enums. There are the following types of interactions:

Axis range manipulation is controlled via QCP::iRangeDrag and QCP::iRangeZoom. When the respective interaction is enabled, the user may drag axes ranges and zoom with the mouse wheel. For details how to control which axes the user may drag/zoom and in what orientations, see QCPAxisRect::setRangeDrag, QCPAxisRect::setRangeZoom, QCPAxisRect::setRangeDragAxes, QCPAxisRect::setRangeZoomAxes.

Plottable selection is controlled by QCP::iSelectPlottables. If QCP::iSelectPlottables is set, the user may select plottables (graphs, curves, bars,...) by clicking on them or in their vicinity (setSelectionTolerance). Whether the user can actually select a plottable can further be restricted with the QCPAbstractPlottable::setSelectable function on the specific plottable. To find out whether a specific plottable is selected, call QCPAbstractPlottable::selected(). To retrieve a list of all currently selected plottables, call selectedPlottables. If you're only interested in QCPGraphs, you may use the convenience function selectedGraphs.

Item selection is controlled by QCP::iSelectItems. If QCP::iSelectItems is set, the user may select items (QCPItemLine, QCPItemText,...) by clicking on them or in their vicinity. To find out whether a specific item is selected, call QCPAbstractItem::selected(). To retrieve a list of all currently selected items, call selectedItems.

Axis selection is controlled with QCP::iSelectAxes. If QCP::iSelectAxes is set, the user may select parts of the axes by clicking on them. What parts exactly (e.g. Axis base line, tick labels, axis label) are selectable can be controlled via QCPAxis::setSelectableParts for each axis. To retrieve a list of all axes that currently contain selected parts, call selectedAxes. Which parts of an axis are selected, can be retrieved with QCPAxis::selectedParts().

Legend selection is controlled with QCP::iSelectLegend. If this is set, the user may select the legend itself or individual items by clicking on them. What parts exactly are selectable can be controlled via QCPLegend::setSelectableParts. To find out whether the legend or any of its child items are selected, check the value of QCPLegend::selectedParts. To find out which child items are selected, call QCPLegend::selectedItems.

All other selectable elements The selection of all other selectable objects (e.g. QCPPlotTitle, or your own layerable subclasses) is controlled with QCP::iSelectOther. If set, the user may select those objects by clicking on them. To find out which are currently selected, you need to check their selected state explicitly.

If the selection state has changed by user interaction, the selectionChangedByUser signal is emitted. Each selectable object additionally emits an individual selectionChanged signal whenever their selection state has changed, i.e. not only by user interaction.

To allow multiple objects to be selected by holding the selection modifier (setMultiSelectModifier), set the flag QCP::iMultiSelect.

Note: In addition to the selection mechanism presented here, QCustomPlot always emits corresponding signals, when an object is clicked or double clicked. see plottableClick and plottableDoubleClick for example.

If many objects, especially plottables, are drawn antialiased, this greatly improves performance during dragging. Thus it creates a more responsive user experience. As soon as the user stops dragging, the last replot is done with normal antialiasing, to restore high image quality.

◆ setNotAntialiasedElements() [1/2]

void QCustomPlot::setNotAntialiasedElements ( const QCP::AntialiasedElements & notAntialiasedElements )

Sets which elements are forcibly drawn not antialiased as an or combination of QCP::AntialiasedElement.

This overrides the antialiasing settings for whole element groups, normally controlled with the setAntialiasing function on the individual elements. If an element is neither specified in setAntialiasedElements nor in setNotAntialiasedElements, the antialiasing setting on each individual element instance is used.

For example, if notAntialiasedElements contains QCP::aePlottables, no plottables will be drawn antialiased, no matter what the specific QCPAbstractPlottable::setAntialiased value was set to.

if an element in notAntialiasedElements is already set in setAntialiasedElements, it is removed from there.

◆ setOpenGl()

void QCustomPlot::setOpenGl	(	bool	enabled,
		int	multisampling = `16`
	)

Warning: This is still an experimental feature and its performance depends on the system that it runs on. Having multiple QCustomPlot widgets in one application with enabled OpenGL rendering might cause context conflicts on some systems.

This method allows to enable OpenGL plot rendering, for increased plotting performance of graphically demanding plots (thick lines, translucent fills, etc.).

If enabled is set to true, QCustomPlot will try to initialize OpenGL and, if successful, continue plotting with hardware acceleration. The parameter multisampling controls how many samples will be used per pixel, it essentially controls the antialiasing quality. If multisampling is set too high for the current graphics hardware, the maximum allowed value will be used.

You can test whether switching to OpenGL rendering was successful by checking whether the according getter QCustomPlot::openGl() returns true. If the OpenGL initialization fails, rendering continues with the regular software rasterizer, and an according qDebug output is generated.

If switching to OpenGL was successful, this method disables label caching (setPlottingHint(QCP::phCacheLabels, false)) and turns on QCustomPlot's antialiasing override for all elements (setAntialiasedElements(QCP::aeAll)), leading to a higher quality output. The antialiasing override allows for pixel-grid aligned drawing in the OpenGL paint device. As stated before, in OpenGL rendering the actual antialiasing of the plot is controlled with multisampling. If enabled is set to false, the antialiasing/label caching settings are restored to what they were before OpenGL was enabled, if they weren't altered in the meantime.

Note: OpenGL support is only enabled if QCustomPlot is compiled with the macro QCUSTOMPLOT_USE_OPENGL defined. This define must be set before including the QCustomPlot header both during compilation of the QCustomPlot library as well as when compiling your application. It is best to just include the line DEFINES += QCUSTOMPLOT_USE_OPENGL in the respective qmake project files.; If you are using a Qt version before 5.0, you must also add the module "opengl" to your QT variable in the qmake project files. For Qt versions 5.0 and higher, QCustomPlot switches to a newer OpenGL interface which is already in the "gui" module.

◆ setSelectionRect()

void QCustomPlot::setSelectionRect ( QCPSelectionRect * selectionRect )

Sets the QCPSelectionRect instance that QCustomPlot will use if mode is not QCP::srmNone and the user performs a click-and-drag interaction. QCustomPlot takes ownership of the passed selectionRect. It can be accessed later via selectionRect.

This method is useful if you wish to replace the default QCPSelectionRect instance with an instance of a QCPSelectionRect subclass, to introduce custom behaviour of the selection rect.

See also: setSelectionRectMode

References mSelectionRect, mSelectionRectMode, processRectSelection(), processRectZoom(), selectionRect(), QCP::srmSelect, and QCP::srmZoom.

◆ setSelectionRectMode()

void QCustomPlot::setSelectionRectMode ( QCP::SelectionRectMode mode )

Sets how QCustomPlot processes mouse click-and-drag interactions by the user.

If mode is QCP::srmNone, the mouse drag is forwarded to the underlying objects. For example, QCPAxisRect may process a mouse drag by dragging axis ranges, see QCPAxisRect::setRangeDrag. If mode is not QCP::srmNone, the current selection rect (selectionRect) becomes activated and allows e.g. rect zooming and data point selection.

If you wish to provide your user both with axis range dragging and data selection/range zooming, use this method to switch between the modes just before the interaction is processed, e.g. in reaction to the mousePress or mouseMove signals. For example you could check whether the user is holding a certain keyboard modifier, and then decide which mode shall be set.

If a selection rect interaction is currently active, and mode is set to QCP::srmNone, the interaction is canceled (QCPSelectionRect::cancel). Switching between any of the other modes will keep the selection rect active. Upon completion of the interaction, the behaviour is as defined by the currently set mode, not the mode that was set when the interaction started.

◆ setSelectionTolerance() [1/2]

void QCustomPlot::setSelectionTolerance ( int pixels )

Sets the tolerance that is used to decide whether a click selects an object (e.g. a plottable) or not.

If the user clicks in the vicinity of the line of e.g. a QCPGraph, it's only regarded as a potential selection when the minimum distance between the click position and the graph line is smaller than pixels. Objects that are defined by an area (e.g. QCPBars) only react to clicks directly inside the area and ignore this selection tolerance. In other words, it only has meaning for parts of objects that are too thin to exactly hit with a click and thus need such a tolerance.

◆ setViewport() [1/2]

void QCustomPlot::setViewport ( const QRect & rect )

Sets the viewport of this QCustomPlot. Usually users of QCustomPlot don't need to change the viewport manually.

The viewport is the area in which the plot is drawn. All mechanisms, e.g. margin caluclation take the viewport to be the outer border of the plot. The viewport normally is the rect() of the QCustomPlot widget, i.e. a rect with top left (0, 0) and size of the QCustomPlot widget.

Don't confuse the viewport with the axis rect (QCustomPlot::axisRect). An axis rect is typically an area enclosed by four axes, where the graphs/plottables are drawn in. The viewport is larger and contains also the axes themselves, their tick numbers, their labels, or even additional axis rects, color scales and other layout elements.

This function is used to allow arbitrary size exports with toPixmap, savePng, savePdf, etc. by temporarily changing the viewport size.

◆ toPainter() [1/2]

void QCustomPlot::toPainter	(	QCPPainter *	painter,

		int	height = `0`
	)

Renders the plot using the passed painter.

The plot is sized to width and height in pixels. If the painter's scale is not 1.0, the resulting plot will appear scaled accordingly.

Note: If you are restricted to using a QPainter (instead of QCPPainter), create a temporary QPicture and open a QCPPainter on it. Then call toPainter with this QCPPainter. After ending the paint operation on the picture, draw it with the QPainter. This will reproduce the painter actions the QCPPainter took, with a QPainter.

◆ legend

QCPLegend * QCustomPlot::legend

A pointer to the default legend of the main axis rect. The legend is invisible by default. Use QCPLegend::setVisible to change this.

QCustomPlot offers convenient pointers to the axes (xAxis, yAxis, xAxis2, yAxis2) and the legend. They make it very easy working with plots that only have a single axis rect and at most one axis at each axis rect side. If you use the layout system to add multiple legends to the plot, use the layout system interface to access the new legend. For example, legends can be placed inside an axis rect's inset layout, and must then also be accessed via the inset layout. If the default legend is removed due to manipulation of the layout system (e.g. by removing the main axis rect), the corresponding pointer becomes 0.

If an axis convenience pointer is currently zero and a new axis rect or a corresponding axis is added in the place of the main axis rect, QCustomPlot resets the convenience pointers to the according new axes. Similarly the legend convenience pointer will be reset if a legend is added after the main legend was removed before.

If one of the four default axes or the default legend is removed due to manipulation of the layout system (e.g. by removing the main axis rect), the corresponding pointers become 0.

If an axis convenience pointer is currently zero and a new axis rect or a corresponding axis is added in the place of the main axis rect, QCustomPlot resets the convenience pointers to the according new axes. Similarly the legend convenience pointer will be reset if a legend is added after the main legend was removed before.

A pointer to the secondary x Axis (top) of the main axis rect of the plot. Secondary axes are invisible by default. Use QCPAxis::setVisible to change this (or use QCPAxisRect::setupFullAxesBox).

QCustomPlot offers convenient pointers to the axes (xAxis, yAxis, xAxis2, yAxis2) and the legend.
