Detailed Description

A chart painter implementation that can paint HiLo charts.

Definition at line 39 of file KDChartHiLoPainter.h.

Constructor & Destructor Documentation

◆ KDChartHiLoPainter()

KDChartHiLoPainter::KDChartHiLoPainter ( KDChartParams * params)
protected

Constructor.

Sets up internal data structures as necessary.

Parameters
paramsthe KDChartParams structure that defines the chart

Definition at line 48 of file KDChartHiLoPainter.cpp.

◆ ~KDChartHiLoPainter()

KDChartHiLoPainter::~KDChartHiLoPainter ( )
protectedvirtual

Destructor.

Definition at line 59 of file KDChartHiLoPainter.cpp.

Member Function Documentation

◆ clipShiftUp()

int KDChartHiLoPainter::clipShiftUp ( bool ,
double  ) const
protectedvirtual

Implements KDChartAxesPainter.

Definition at line 104 of file KDChartHiLoPainter.cpp.

◆ fallbackLegendText()

TQString KDChartHiLoPainter::fallbackLegendText ( uint dataset) const
protectedvirtual

This method is a specialization that returns a fallback legend text appropriate for HiLo that do not have the same notion of a dataset like e.g.

bars.

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 78 of file KDChartHiLoPainter.cpp.

◆ isNormalMode()

bool KDChartHiLoPainter::isNormalMode ( ) const
protectedvirtual

Implements KDChartAxesPainter.

Definition at line 99 of file KDChartHiLoPainter.cpp.

◆ numLegendFallbackTexts()

uint KDChartHiLoPainter::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.
