ChartHitInfo.InConstantLine Property

Gets a value indicating whether the test point is within the constant line.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v24.1.dll

NuGet Package: DevExpress.Charts

Declaration

C#

public bool InConstantLine { get; }

VB.NET

Public ReadOnly Property InConstantLine As Boolean

Property Value

Type	Description
Boolean	true if the test point is within a constant line; otherwise, false.

Remarks

The InConstantLine property is useful if you don’t need to determine the exact element residing under the test point and are only interested in whether the point is within a constant line. For instance, the property can be used if you need to provide a common context menu for a constant line regardless of which particular constant line element was right-clicked. If you need to obtain a particular element located under the test point, use the ChartHitInfo.HitTest property.
