Detailed Description

Holds multiple axes and arranges them in a rectangular shape.

This class represents an axis rect, a rectangular area that is bounded on all sides with an arbitrary number of axes.

Initially QCustomPlot has one axis rect, accessible via QCustomPlot::axisRect(). 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 axis by providing the respective axis type (QCPAxis::AxisType) and index. If you need all axes in the axis rect, use axes. The top and right axes are set to be invisible initially (QCPAxis::setVisible). To add more axes to a side, use addAxis or addAxes. To remove an axis, use removeAxis.

The axis rect layerable itself only draws a background pixmap or color, if specified (setBackground). It is placed on the "background" layer initially (see 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 QCPLayoutInset. It is accessible via 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 setRangeDrag and setRangeDragAxes. If the mouse wheel is scrolled while the cursor is on the axis rect, certain axes are scaled. This is controllable via setRangeZoom, setRangeZoomAxes and setRangeZoomFactor. These interactions are only enabled if QCustomPlot::setInteractions contains QCP::iRangeDrag and QCP::iRangeZoom.

Member Function Documentation

QList< QCPAxis * > QCPAxisRect::addAxes ( QCPAxis::AxisTypes types )

Adds a new axis with addAxis to each axis rect side specified in types. This may be an or-combination of QCPAxis::AxisType, so axes can be added to multiple sides at once.

Returns a list of the added axes.

See also: addAxis, setupFullAxesBox

Definition at line 12412 of file qcustomplot.cpp.

QCPAxis * QCPAxisRect::addAxis	(	QCPAxis::AxisType	type,
		QCPAxis *	axis = `0`
	)

Adds a new axis to the axis rect side specified with type, and returns it. If axis is 0, a new QCPAxis instance is created internally.

You may inject QCPAxis instances (or sublasses of QCPAxis) by setting axis to an axis that was previously created outside QCustomPlot. It is important to note that QCustomPlot takes ownership of the axis, so you may not delete it afterwards. Further, the axis must have been created with this axis rect as parent and with the same axis type as specified in type. If this is not the case, a debug output is generated, the axis is not added, and the method returns 0.

This method can not be used to move axis between axis rects. The same axis instance must not be added multiple times to the same or different axis rects.

If an axis rect side already contains one or more axes, the lower and upper endings of the new axis (QCPAxis::setLowerEnding, QCPAxis::setUpperEnding) are set to QCPLineEnding::esHalfBar.

int QCPAxisRect::right ( ) const

inline

Returns the pixel position of the right border of this axis rect. Margins are not taken into account here, so the returned value is with respect to the inner rect.

Definition at line 2076 of file qcustomplot.h.

void QCPAxisRect::setBackground ( const QPixmap & pm )

Sets pm as the axis background pixmap. The axis background pixmap will be drawn inside the axis rect. Since axis rects place themselves on the "background" layer by default, the axis rect backgrounds are usually drawn below everything else.

For cases where the provided pixmap doesn't have the same size as the axis rect, scaling can be enabled with setBackgroundScaled and the scaling mode (i.e. 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.

Below the pixmap, the axis rect may be optionally filled with a brush, if specified with setBackground(const QBrush &brush).

See also: setBackgroundScaled, setBackgroundScaledMode, setBackground(const QBrush &brush)

Definition at line 12698 of file qcustomplot.cpp.

void QCPAxisRect::setBackground	(	const QPixmap &	pm,
		bool	scaled,
		Qt::AspectRatioMode	mode = `Qt::KeepAspectRatioByExpanding`
	)

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

Allows setting the background pixmap of the axis rect, whether it shall be scaled and how it shall be scaled in one call.

See also: setBackground(const QPixmap &pm), setBackgroundScaled, setBackgroundScaledMode

Definition at line 12729 of file qcustomplot.cpp.

void QCPAxisRect::setBackground ( const QBrush & brush )

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

Sets brush as the background brush. The axis rect background will be filled with this brush. Since axis rects place themselves on the "background" layer by default, the axis rect backgrounds are usually drawn below everything else.

The brush will be drawn before (under) any background pixmap, which may be specified with setBackground(const QPixmap &pm).

To disable drawing of a background brush, set brush to Qt::NoBrush.

See also: setBackground(const QPixmap &pm)

Definition at line 12717 of file qcustomplot.cpp.

void QCPAxisRect::setBackgroundScaled ( bool scaled )

Sets whether the axis background pixmap shall be scaled to fit the axis rect or not. If scaled is set to true, you may 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 axis rect dimensions are changed continuously.)

See also: setBackground, setBackgroundScaledMode

Definition at line 12747 of file qcustomplot.cpp.

void QCPAxisRect::setBackgroundScaledMode ( Qt::AspectRatioMode mode )

If scaling of the axis background pixmap is enabled (setBackgroundScaled), use this function to define whether and how the aspect ratio of the original pixmap passed to setBackground is preserved.

See also: setBackground, setBackgroundScaled

Definition at line 12757 of file qcustomplot.cpp.

void QCPAxisRect::setRangeDrag ( Qt::Orientations orientations )

Sets which axis orientation may be range dragged by the user with mouse interaction. What orientation corresponds to which specific axis can be set with setRangeDragAxes(QCPAxis *horizontal, QCPAxis *vertical). By default, the horizontal axis is the bottom axis (xAxis) and the vertical axis is the left axis (yAxis).

To disable range dragging entirely, pass 0 as orientations or remove QCP::iRangeDrag from QCustomPlot::setInteractions. To enable range dragging for both directions, pass Qt::Horizontal | Qt::Vertical as orientations.

In addition to setting orientations to a non-zero value, make sure QCustomPlot::setInteractions contains QCP::iRangeDrag to enable the range dragging interaction.

See also: setRangeZoom, setRangeDragAxes, setNoAntialiasingOnDrag

Definition at line 12808 of file qcustomplot.cpp.

void QCPAxisRect::setRangeDragAxes	(	QCPAxis *	horizontal,
		QCPAxis *	vertical
	)

Sets the axes whose range will be dragged when setRangeDrag enables mouse range dragging on the QCustomPlot widget.

See also: setRangeZoomAxes

Definition at line 12839 of file qcustomplot.cpp.

void QCPAxisRect::setRangeZoom ( Qt::Orientations orientations )

Sets which axis orientation may be zoomed by the user with the mouse wheel. What orientation corresponds to which specific axis can be set with setRangeZoomAxes(QCPAxis *horizontal, QCPAxis *vertical). By default, the horizontal axis is the bottom axis (xAxis) and the vertical axis is the left axis (yAxis).

To disable range zooming entirely, pass 0 as orientations or remove QCP::iRangeZoom from QCustomPlot::setInteractions. To enable range zooming for both directions, pass Qt::Horizontal | Qt::Vertical as orientations.

In addition to setting orientations to a non-zero value, make sure QCustomPlot::setInteractions contains QCP::iRangeZoom to enable the range zooming interaction.

void QCPAxisRect::setRangeZoomAxes	(	QCPAxis *	horizontal,
		QCPAxis *	vertical
	)

Sets the axes whose range will be zoomed when setRangeZoom enables mouse wheel zooming on the QCustomPlot widget. The two axes can be zoomed with different strengths, when different factors are passed to setRangeZoomFactor(double horizontalFactor, double verticalFactor).

See also: setRangeDragAxes

Definition at line 12852 of file qcustomplot.cpp.

void QCPAxisRect::setRangeZoomFactor	(	double	horizontalFactor,
		double	verticalFactor
	)

Sets how strong one rotation step of the mouse wheel zooms, when range zoom was activated with setRangeZoom. The two parameters horizontalFactor and verticalFactor provide a way to let the horizontal axis zoom at different rates than the vertical axis. Which axis is horizontal and which is vertical, can be set with setRangeZoomAxes.

When the zoom factor is greater than one, scrolling the mouse wheel backwards (towards the user) will zoom in (make the currently visible range smaller). For zoom factors smaller than one, the same scrolling direction will zoom out.

Definition at line 12868 of file qcustomplot.cpp.

void QCPAxisRect::setRangeZoomFactor ( double factor )

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

Sets both the horizontal and vertical zoom factor.

Definition at line 12878 of file qcustomplot.cpp.

void QCPAxisRect::setupFullAxesBox ( bool connectRanges = false )

Convenience function to create an axis on each side that doesn't have any axes yet and set their visibility to true. Further, the top/right axes are assigned the following properties of the bottom/left axes:

range (QCPAxis::setRange)
range reversed (QCPAxis::setRangeReversed)
scale type (QCPAxis::setScaleType)
scale log base (QCPAxis::setScaleLogBase)
ticks (QCPAxis::setTicks)
auto (major) tick count (QCPAxis::setAutoTickCount)
sub tick count (QCPAxis::setSubTickCount)
auto sub ticks (QCPAxis::setAutoSubTicks)
tick step (QCPAxis::setTickStep)
auto tick step (QCPAxis::setAutoTickStep)
number format (QCPAxis::setNumberFormat)
number precision (QCPAxis::setNumberPrecision)
tick label type (QCPAxis::setTickLabelType)
date time format (QCPAxis::setDateTimeFormat)
date time spec (QCPAxis::setDateTimeSpec)

Tick labels (QCPAxis::setTickLabels) of the right and top axes are set to false.

If connectRanges is true, the rangeChanged signals of the bottom and left axes are connected to the QCPAxis::setRange slots of the top and right axes.
