Axis2D.StripItemsSource Property

Gets or sets the collection of objects used to generate strips.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v24.1.dll

NuGet Package: DevExpress.Wpf.Charts

Declaration

public IEnumerable StripItemsSource { get; set; }

Property Value

Type Description
IEnumerable

A collection that is used to generate strips. The default is null (Nothing in Visual Basic).

Example

This example shows how to create horizontal strips for the y-axis based on a View Model’s collection of objects.

Strips are generated for the y-axis

To generate custom strips from a ViewModel, bind an axis’s StripItemsSource to a collection of objects that contain strip settings. Then, use the Axis2D.StripItemTemplate or Axis2D.StripItemTemplateSelector property to specify how to display the generated strips.
