Constructor & Destructor Documentation
KDChartPolarPainter::KDChartPolarPainter | ( | 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

Member Function Documentation
void KDChartPolarPainter::paintData | ( | QPainter * | painter, | |
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 and the chart is configured to be drawn with markers.
- 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 KDChartPainter.

QString KDChartPolarPainter::fallbackLegendText | ( | uint | dataset | ) | const [protected, virtual] |
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:
-
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 KDChartPolarPainter::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
