WebChartControl.PivotChartingCustomizeLegend Event

Occurs before automatic settings are applied to the legend's layout properties.

Namespace:DevExpress.XtraCharts.Web
Assembly:DevExpress.XtraCharts.v17.2.Web.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type CustomizeLegendEventArgs containing data related to this event.

The following CustomizeLegendEventArgs 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.

Expanded Remarks

When a familiar data source (such as the ASPxPivotGrid) is assigned to the chart's ASPxDataWebControlBase.DataSourceID property, and the AutoLayoutSettingsEnabled property is turned on, the DevExpress.XtraCharts.Legend.MaxHorizontalPercentage and DevExpress.XtraCharts.Legend.MaxVerticalPercentage properties are defined automatically, and cannot be customized at design time.

Handle the PivotChartingCustomizeLegend event to manually adjust these options (via the DevExpress.XtraCharts.CustomizeLegendEventArgs.MaxHorizontalPercentage and DevExpress.XtraCharts.CustomizeLegendEventArgs.MaxVerticalPercentage properties). To access the legend, use the DevExpress.XtraCharts.CustomizeLegendEventArgs.Legend property.

For more information, see Pivot Charting (Integration with a Pivot Grid Control).
