Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v24.1.UI.dll

NuGet Package: DevExpress.Win.Charts

Declaration

C#

public event CustomizeLegendEventHandler PivotChartingCustomizeLegend

VB.NET

Public Event PivotChartingCustomizeLegend As CustomizeLegendEventHandler

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 PivotGridControl) is assigned to the chart’s ChartControl.DataSource property, and the ChartControl.AutoLayoutSettingsEnabled property is turned on, the LegendBase.MaxHorizontalPercentage and LegendBase.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.
