Specifies whether a user can explode pie slices with the mouse pointer at runtime.
Namespace: DevExpress.XtraCharts
Assembly: DevExpress.XtraCharts.v24.1.dll
NuGet Package: DevExpress.Charts
Declaration
[TypeConverter(typeof(BooleanTypeConverter))]
[XtraChartsLocalizableCategory(XtraChartsCategory.Behavior)]
[XtraSerializableProperty]
public bool RuntimeExploding { get; set; }
Property Value
Type | Description |
---|---|
Boolean | true, if a user can drag pie slices; otherwise, false. |
Remarks
The RuntimeExploding property is in effect when the ChartControl.RuntimeHitTesting property is set to true.
The animation below shows how a user can move out a pie slice at runtime:
Use the the PieSeriesViewBase.ExplodedDistancePercentage property to increase/decrease the distance between an exploded slice and the rest of the pie.
private void OnLoad(object sender, EventArgs e) {
chartControl1.RuntimeHitTesting = true;
PieSeriesView view = chartControl1.Series[0].View as PieSeriesView;
view.RuntimeExploding = true;
view.ExplodedDistancePercentage = 20;
}
For the WebChartControl, enable RuntimeExploding and add points that a user clicks to the PieSeriesViewBase.ExplodedPoints collection in the WebChartControl.ObjectSelected event handler.
