Binds the data members to the appropriate data point properties.
protected override void BindMembers()Overrides:
Creates the data model for the pie series and initializes the data point collection.
protected override ChartDataPointCollection CreateModel()A ChartDataPointCollection containing the pie data points.
Overrides:
Creates a visual element for the specified pie data point.
protected override DataPointElement CreatePointElement(DataPoint point)The data point for which to create the visual element.
Returns:A DataPointElement representing the pie segment.
Overrides:
Releases the managed resources used by the pie series.
protected override void DisposeManagedResources()Overrides:
Gets the palette entry for the pie segment at the specified index.
public PaletteEntry GetPieSegmentColors(int i)The index of the pie segment.
Returns:A PaletteEntry containing the colors for the segment, or null if no palette is available.
Applies the current palette to all pie point elements, setting their background and border colors.
protected override void OnApplyPalette()Overrides:
Called when the series is attached to a parent chart element.
protected override void OnAttached(UIChartElement parent)The parent chart element, which must be a PieArea.
Overrides:
Called when the series is detached from its parent chart element.
protected override void OnDettached()Overrides:
Raises the property changed event and updates the data model.
protected override void OnNotifyPropertyChanged(string propertyName)The name of the property that changed.
Overrides:
Validates that the specified data point is compatible with this pie series.
protected override void ValidatePoint(DataPoint item)The data point to validate.
