- 2 minutes to read
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.
