Constructor & Destructor Documentation
| 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

| KDChartTableDataBase * | data, | |||
| bool | paint2nd, | |||
| KDChartDataRegionList * | regions = 0 | |||
| ) | [protected, virtual] |
Paints the actual data area.
Data regions will only be added if regions is not 0.
- Parameters:
-
painter the QPainter 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
Reimplemented from KDChartAxesPainter.
Reimplemented in KDChartAreaPainter.
