WebChartControl.PivotChartingCustomizeLegend Event
Occurs before automatic settings are applied to the legend‘s layout properties.
Namespace: DevExpress.XtraCharts.Web
Assembly: DevExpress.XtraCharts.v18.2.Web.dll
Declaration
Event Data
The PivotChartingCustomizeLegend event's data class is CustomizeLegendEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Legend | Gets the chart’s legend. |
| MaxHorizontalPercentage | Specifies the legend‘s maximum horizontal percentage. |
| MaxVerticalPercentage | Specifies the legend‘s maximum vertical percentage. |
Remarks
When a familiar data source (such as the ASPxPivotGrid) is assigned to the chart’s ASPxDataWebControlBase.DataSourceID property, and the WebChartControl.AutoLayoutSettingsEnabled property is turned on, the Legend.MaxHorizontalPercentage and Legend.MaxVerticalPercentage properties are defined automatically, and cannot be customized at design time.
Handle the PivotChartingCustomizeLegend event to manually adjust these options (via the CustomizeLegendEventArgs.MaxHorizontalPercentage and CustomizeLegendEventArgs.MaxVerticalPercentage properties). To access the legend, use the CustomizeLegendEventArgs.Legend property.
