Represents a diagram that is used to plot non-XY 2D series.
Namespace: DevExpress.Xpf.Charts
Assembly: DevExpress.Xpf.Charts.v24.2.dll
NuGet Package: DevExpress.Wpf.Charts
#Declaration
#Remarks
After you set the ChartControl.Diagram property to the SimpleDiagram2D
type, only a series of the PieSeries2D types can be added to the Diagram.Series collection.
For more information, refer to Diagram and Series Type Compatibility.
#Example
This example demonstrates how to create a 2D Pie chart.
Create a ChartControl and specify its ChartControl.Diagram property to a SimpleDiagram2D

Use the following properties to bind the series to data:
- Series.DataSource - Specifies the series’s data source.
- Series.ArgumentDataMember - Defines the data member that provides the series’s arguments.
- Series.ValueDataMember - Specifies the data member that provides the series’s values.
The PieSeries2D.Model property allows you to change the series appearance using the built-in models. This example uses the GlarePie2DModel model.
Use the Series.LegendTextPattern property to specify how to format text that identifies series points in the legend.
Set the Series.LabelsVisibility property to true to display the series’s labels. The SeriesLabel.TextPattern property defines how to configure series labels’ text.
The PieTotalLabel.TextPattern property allows you to specify the center label’s content.
