Member Enumeration Documentation

◆ LayerInsertMode

enum QCustomPlot::LayerInsertMode

Defines how a layer should be inserted relative to an other layer.

See also: addLayer, moveLayer

Enumerator
limBelow	Layer is inserted below other layer.
limAbove	Layer is inserted above other layer.

Definition at line 1676 of file qcustomplot.h.

◆ RefreshPriority

enum QCustomPlot::RefreshPriority

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

See also: replot

Enumerator
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.

Definition at line 1686 of file qcustomplot.h.

Constructor & Destructor Documentation

◆ QCustomPlot()

QCustomPlot::QCustomPlot ( QWidget * parent = 0 )

explicit

Constructs a QCustomPlot and sets reasonable default values.

Definition at line 9072 of file qcustomplot.cpp.

◆ ~QCustomPlot()

QCustomPlot::~QCustomPlot ( )

virtual

Definition at line 9144 of file qcustomplot.cpp.

Member Function Documentation

◆ addGraph()

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

Definition at line 9752 of file qcustomplot.cpp.

◆ 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 9893 of file qcustomplot.cpp.

◆ addLayer()

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.

See also: layer, moveLayer, removeLayer

Definition at line 10138 of file qcustomplot.cpp.

◆ 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).

See also: plottable, plottableCount, removePlottable, clearPlottables

Definition at line 9550 of file qcustomplot.cpp.

◆ afterReplot

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.

See also: replot, beforeReplot

◆ axisRect()

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).

See also: axisRectCount, axisRects

Definition at line 10260 of file qcustomplot.cpp.

◆ axisRectCount()

int QCustomPlot::axisRectCount ( ) const

Returns the number of axis rects in the plot.

◆ mouseMove

void QCustomPlot::mouseMove ( QMouseEvent * event )

signal

This signal is emitted when the QCustomPlot receives a mouse move event.

It is emitted before QCustomPlot handles any other mechanism like range dragging. So a slot connected to this signal can still influence the behaviour e.g. with QCPAxisRect::setRangeDrag or QCPAxisRect::setRangeDragAxes.

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()

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

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.

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.

◆ saveBmp()

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 JPG 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.

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.

JPG 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 JPG format isn't supported by the system, see Qt docs about QImageWriter::supportedImageFormats().

		bool	noCosmeticPen = `false`,
		int	width = `0`,
		int	height = `0`,
		const QString &	pdfCreator = `""`,
		const QString &	pdfTitle = `""`
	)

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).
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.

pdfCreator and pdfTitle may be used to set the according metadata fields in the resulting PDF file.

Note: On Android systems, this method does nothing and issues an according qDebug warning message. This is also the case if for other reasons the define flag QT_NO_PRINTER is set.

Saves a PNG image file to fileName on disc.

Line widths and texts etc. are not scaled up when larger widths/heights are used. If you want that effect, use the scale parameter.

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 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. (width 100 and scale 2.0 lead to a full resolution file with width 200.) If the format supports compression, quality may be between 0 and 100 to control it.

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

signal

This signal is emitted after the user has changed the selection in the QCustomPlot, e.g.

See also: setNotAntialiasedElement

Definition at line 9193 of file qcustomplot.cpp.

◆ setAntialiasedElements()

void QCustomPlot::setAntialiasedElements ( const QCP::AntialiasedElements & antialiasedElements )

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.

◆ setBackground() [1/3]

void QCustomPlot::setBackground ( const QBrush & brush )

Sets the background brush of the viewport (see setViewport).

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.

See also: setBackgroundScaled, setBackgroundScaledMode

Definition at line 9458 of file qcustomplot.cpp.

◆ setBackground() [2/3]

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.

void QCustomPlot::setBackgroundScaled ( bool scaled )

Sets whether the viewport background pixmap shall be scaled to fit the viewport.

If scaled is set to true, control whether and how the aspect ratio of the original pixmap is preserved with setBackgroundScaledMode.

Note that the scaled version of the original pixmap is buffered, so there is no performance penalty on replots. (Except when the viewport dimensions are changed continuously.)

bool QCustomPlot::setCurrentLayer ( QCPLayer * layer )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.Sets the provided layer to be the current layer.

Returns true on success, i.e. when layer is a valid layer in the QCustomPlot.

◆ setInteraction()

void QCustomPlot::setInteraction	(	const QCP::Interaction &	interaction,
		bool	enabled = `true`
	)

Sets the single interaction of this QCustomPlot to enabled.

For details about the interaction system, see setInteractions.

See also: setInteractions

Definition at line 9328 of file qcustomplot.cpp.

◆ setInteractions()

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 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.

See also: setInteraction, setSelectionTolerance

Definition at line 9316 of file qcustomplot.cpp.

◆ setMultiSelectModifier()

void QCustomPlot::setMultiSelectModifier ( Qt::KeyboardModifier modifier )

Sets the keyboard modifier that will be recognized as multi-select-modifier.

If QCP::iMultiSelect is specified in setInteractions, the user may select multiple objects by clicking on them one after the other while holding down modifier.

By default the multi-select-modifier is set to Qt::ControlModifier.

Definition at line 9405 of file qcustomplot.cpp.

◆ setNoAntialiasingOnDrag()

void QCustomPlot::setNoAntialiasingOnDrag ( bool enabled )

Sets whether antialiasing is disabled for this QCustomPlot while the user is dragging axes ranges.

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.

Definition at line 9363 of file qcustomplot.cpp.

◆ setNotAntialiasedElement()

void QCustomPlot::setNotAntialiasedElement	(	QCP::AntialiasedElement	notAntialiasedElement,
		bool	enabled = `true`
	)

Sets whether the specified notAntialiasedElement is forcibly drawn not antialiased.

See setNotAntialiasedElements for details.

See also: setAntialiasedElement

Definition at line 9239 of file qcustomplot.cpp.

◆ setNotAntialiasedElements()

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.

Definition at line 9223 of file qcustomplot.cpp.

◆ setPlottingHint()

void QCustomPlot::setPlottingHint	(	QCP::PlottingHint	hint,
		bool	enabled = `true`
	)

Sets the specified plotting hint to enabled.

See also: setPlottingHints

Definition at line 9383 of file qcustomplot.cpp.

◆ setPlottingHints()

void QCustomPlot::setPlottingHints ( const QCP::PlottingHints & hints )

Sets the plotting hints for this QCustomPlot instance as an or combination of QCP::PlottingHint.

See also: setPlottingHint

Definition at line 9373 of file qcustomplot.cpp.

◆ setSelectionTolerance()

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.

See also: setInteractions, QCPLayerable::selectTest

Definition at line 9349 of file qcustomplot.cpp.

◆ setViewport()

void QCustomPlot::setViewport ( const QRect & rect )

Sets the viewport of this QCustomPlot.

The Viewport is the area that the top level layout (QCustomPlot::plotLayout()) uses as its rect. Normally, the viewport is the entire widget rect.

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

◆ titleClick

void QCustomPlot::titleClick	(	QMouseEvent *	event,
		QCPPlotTitle *	title
	)

signal

This signal is emitted when a plot title is clicked.

event is the mouse event that caused the click and title is the plot title that received the click.

See also: titleDoubleClick

◆ titleDoubleClick

void QCustomPlot::titleDoubleClick	(	QMouseEvent *	event,
		QCPPlotTitle *	title
	)

signal

This signal is emitted when a plot title is double clicked.

event is the mouse event that caused the click and title is the plot title that received the click.

See also: titleClick

◆ toPainter()

void QCustomPlot::toPainter	(	QCPPainter *	painter,
		int	width = `0`,
		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.

◆ toPixmap()

QPixmap QCustomPlot::toPixmap	(	int	width = `0`,
		int	height = `0`,
		double	scale = `1.0`
	)

Renders the plot to a pixmap and returns it.

The plot is sized to width and height in pixels and scaled with scale. (width 100 and scale 2.0 lead to a full resolution pixmap with width 200.)

◆ updateLayerIndices()

void QCustomPlot::updateLayerIndices ( ) const

protected

Definition at line 11026 of file qcustomplot.cpp.

◆ viewport()

QRect QCustomPlot::viewport ( ) const

inline

Returns the viewport rect of this QCustomPlot instance.

The viewport is the area the plot is drawn in, 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, the plot title etc.

Only when saving to a file (see savePng, savePdf etc.) the viewport is temporarily modified to allow saving plots with sizes independent of the current widget size.

◆ 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.
