Member Function Documentation

paintData()

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

protectedvirtual

Paints the actual data area.

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
