Layout manager for parasite plots

QwtParasitePlotLayout manages the layout of parasite plots that share the same canvas area with their host plot. It copies layout attributes from the host plot to ensure visual consistency.

参见: QwtPlot::createParasitePlot()

成员函数说明

◆ activate()

void QwtParasitePlotLayout::activate	(	const QwtPlot *	plot,
		const QRectF &	plotRect,
		Options	options = `Options()`
	)

overridevirtual

Activate the layout for a parasite plot

Copies all layout attributes from the host plot to maintain visual consistency. If no host plot is found, uses default layout behavior.

参数

plot	Parasite plot to activate layout for
plotRect	Rectangle for the plot area
options	Layout options

重载 QwtPlotLayout .

◆ minimumSizeHint()

QSize QwtParasitePlotLayout::minimumSizeHint ( const QwtPlot * plot ) const

overridevirtual

Get minimum size hint for a parasite plot

Returns the minimum size from the host plot's layout if available, otherwise uses default QwtPlotLayout behavior.

参数

plot	Parasite plot to get size hint for

返回: Minimum size hint

重载 QwtPlotLayout .

◆ parasiteScaleRect()

QRectF QwtParasitePlotLayout::parasiteScaleRect ( QwtAxisId aid ) const

Get the parasite axis scale rect without offset

Returns the scale rectangle for a parasite axis before it was copied from the host plot layout. This is the original unmodified position.

参数

aid	Axis ID to get scale rect for

返回: Scale rectangle for the axis
