Doughnut Series

The DoughnutSeries visualizes its data points in doughnut segments.

Properties

DoughnutSeries class inherits from the PieSeries class - See the inherited properties.

• InnerRadiusFactor (double): Gets or sets the inner radius factor of the series (that is the space that remains empty). The value is in logical units, in the range of [0, 1].

Example

The following code demonstrates how to setup a DoughnutSeries using RadPieChart:

Add an xmlns definition to Telerik controls:

xmlns:telerik="using:Telerik.UI.Xaml.Controls.Chart"

Declare the RadPieChart and the DoughnutSeries:

<telerik:RadPieChartx:Name="mychart" Width="300" Height="300" ClipToBounds="False" PaletteName="DefaultDark">
    <telerik:DoughnutSeries ShowLabels="True">
        <telerik:DoughnutSeries.ValueBinding>
            <telerik:PropertyNameDataPointBinding PropertyName="Value"/>
        </telerik:DoughnutSeries.ValueBinding>
    </telerik:DoughnutSeries>
</telerik:RadPieChart>

Create sample data.

public class Data
{
    public double Value { get; set; }
}

public List<Data> CreateData()
{
    List<Data> data = new List<Data>();
    data.Add(new Data() { Value = 20 });
    data.Add(new Data() { Value = 45 });
    data.Add(new Data() { Value = 35 });

    return data;
}

Pass the data to the ItemsSource of the series.

this.mychart.Series[0].ItemsSource = CreateData();
