Range.AutoSideMargins Property

Specifies whether a space should be left between the outermost series point and the diagram’s edge, when it is scrolled.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v23.2.dll

NuGet Package: DevExpress.Charts

Declaration

C#

public bool AutoSideMargins { get; set; }

VB.NET

Public Property AutoSideMargins As Boolean

Property Value

Type	Description
Boolean	true, if the series are plotted with indents; otherwise, false.

Remarks

Use the AutoSideMargins property, to force an axis to automatically extend its scrolling range so that indents are preserved on both ends of the axis.

The following images demonstrate how the AutoSideMargins property works.

AutoSideMargins = true	AutoSideMargins = false

For more information, refer to Visual Ranges and Whole Ranges .

Example

This example demonstrates how to use the AxisBase.VisualRange property to define the visible range of an axis, and the AxisBase.WholeRange property to define its whole range.

For more information on axis range, refer to Visual Ranges and Whole Ranges .
