Specifies the template that defines the presentation of the Crosshair Cursor’s axis labels for the X-axis (Y-axis). This is a dependency property.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v23.2.dll

NuGet Package: DevExpress.Wpf.Charts

Declaration

C#

public DataTemplate CrosshairLabelTemplate { get; set; }

VB.NET

Public Property CrosshairLabelTemplate As DataTemplate

Property Value

Type	Description
DataTemplate	The template defining the presentation of the Crosshair Cursor’s axis labels.

Remarks

This template uses the CrosshairAxisLabelPresentationData class’ object as the data context.

Example

This example shows how to customize the visual representation of axis crosshair labels via their template.

To accomplish this, it is necessary to create a DataTemplate object that specifies the appearance of axis crosshair labels, and assign it to the Axis2D.CrosshairLabelTemplate property.
