Diagram.SeriesItemTemplate Property

Gets or sets the DataTemplate that specifies how to convert a model object to a series.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v24.2.dll

NuGet Package: DevExpress.Wpf.Charts

Declaration

C#

public DataTemplate SeriesItemTemplate { get; set; }

VB.NET

Public Property SeriesItemTemplate As DataTemplate

Property Value

Type	Description
DataTemplate	A DataTemplate that specifies the visualization of the series data objects. The default is null (Nothing in Visual Basic).

Example

This example demonstrates how to bind series view models to a chart. Note that you can bind secondary axes and custom labels using the same approach.

To bind series view models to a chart, use the Diagram.SeriesItemsSource property. To configure how the series view model is converted to a series on a chart, use Diagram.SeriesItemTemplate or Diagram.SeriesItemTemplateSelector. In this example, the Template is used to generate identical series.

    Public Property CountryName() As String
    Public Property Values() As IEnumerable(Of Gdp)

Public Class Gdp
