Paints the actual data area and registers the region for the data points 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
Implements KDChartAxesPainter.

QString KDChartBWPainter::fallbackLegendText | ( | uint | dataset | ) | const [protected, virtual] |
This method is a specialization that returns a fallback legend text appropriate for BW 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:
-
uint dataset the dataset number for which to generate a fallback text
- Returns:
- the fallback text to use for describing the specified dataset in the legend

uint KDChartBWPainter::numLegendFallbackTexts | ( | KDChartTableDataBase * | data | ) | const [protected, virtual] |
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
