Detailed Description

A chart painter implementation that can paint polar charts.

Definition at line 36 of file KDChartPolarPainter.h.

Constructor & Destructor Documentation

◆ KDChartPolarPainter()

KDChartPolarPainter::KDChartPolarPainter ( KDChartParams * params)
protected

Constructor.

Sets up internal data structures as necessary.

Parameters
paramsthe KDChartParams structure that defines the chart
datathe data that will be displayed as a chart

Definition at line 49 of file KDChartPolarPainter.cpp.

◆ ~KDChartPolarPainter()

KDChartPolarPainter::~KDChartPolarPainter ( )
protectedvirtual

Destructor.

Definition at line 60 of file KDChartPolarPainter.cpp.

Member Function Documentation

◆ fallbackLegendText()

TQString KDChartPolarPainter::fallbackLegendText ( uint dataset) const
protectedvirtual

This method is a specialization that returns a fallback legend text appropriate for polar charts where the fallbacks should come from the values, not from the datasets.

This method is only used when automatic legends are used, because manual and first-column legends do not need fallback texts.

Parameters
uintdataset the dataset number for which to generate a fallback text
Returns
the fallback text to use for describing the specified dataset in the legend

Reimplemented from KDChartPainter.

Definition at line 781 of file KDChartPolarPainter.cpp.

◆ numLegendFallbackTexts()

uint KDChartPolarPainter::numLegendFallbackTexts ( KDChartTableDataBase * data) const
protectedvirtual

This methods returns the number of elements to be shown in the legend in case fallback texts are used.

This method is only used when automatic legends are used, because manual and first-column legends do not need fallback texts.

Returns
the number of fallback texts to use

Reimplemented from KDChartPainter.

Definition at line 796 of file KDChartPolarPainter.cpp.

◆ paintData()

void KDChartPolarPainter::paintData ( TQPainter * painter,
KDChartTableDataBase * data,
bool paint2nd,
KDChartDataRegionList * regions = 0 )
protectedvirtual

Paints the actual data area.

Data regions will only be added if regions is not 0 and the chart is configured to be drawn with markers.

Parameters
painterthe TQPainter onto which the chart should be painted
datathe data that will be displayed as a chart
paint2ndspecifies whether the main chart or the additional chart is to be drawn now
regionsa pointer to a list of regions that will be filled with regions representing the data segments, if not null

Implements KDChartPainter.
