How to: Create a 2D Pie (Donut) Chart

  • 3 minutes to read

This example demonstrates how to create a 2D Pie chart.

Pie chart

Create a ChartControl and specify its ChartControl.Diagram property to a SimpleDiagram2D object.

Note

Note that the ChartControl.Diagram is a content property. You can declare a diagram in XAML directly after a chart control’s declaration without wrapping it in opening and closing ChartControl.Diagram tags.

Add a PieSeries2D object to the Diagram.Series collection.

Note

Note that the Diagram.Series is a content property. You can declare series in XAML directly after a diagram’s declaration without wrapping them in opening and closing Diagram.Series tags.

Use the following properties to bind the series to data:

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.
