VB.NET

<XtraChartsLocalizableCategory(XtraChartsCategory.Behavior)>
Public Property HorizontalIndent As Integer

Property Value

Type	Description
Int32	An integer value that specifies the horizontal indent in pixels.

Remarks

Use the HorizontalIndent property, to specify the horizontal indent between legend items.

To control the vertical indent between legend items, use the similar LegendBase.VerticalIndent property.

Example

This example demonstrates how to access a chart’s Legend and customize its appearance at runtime.
