Event Data

The CustomizeLegend 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.


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

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