Detailed Description

A chart painter implementation that can paint line charts.

Definition at line 38 of file KDChartLinesPainter.h.

Constructor & Destructor Documentation

◆ KDChartLinesPainter()

KDChartLinesPainter::KDChartLinesPainter ( KDChartParams * params )

protected

Constructor.

Sets up internal data structures as necessary.

Parameters

params	the KDChartParams structure that defines the chart
data	the data that will be displayed as a chart

Definition at line 50 of file KDChartLinesPainter.cpp.

◆ ~KDChartLinesPainter()

KDChartLinesPainter::~KDChartLinesPainter ( )

protectedvirtual

Destructor.

Definition at line 61 of file KDChartLinesPainter.cpp.

Member Function Documentation

◆ clipShiftUp()

int KDChartLinesPainter::clipShiftUp	(	bool	,

protectedvirtual

Paints the actual data area.

Data regions will only be added if regions is not 0.

Parameters

painter	the TQPainter onto which the chart should be painted
data	the data that will be displayed as a chart
paint2nd	specifies whether the main chart or the additional chart is to be drawn now
regions	a pointer to a list of regions that will be filled with regions representing the data segments, if not null
