Doughnut Series

The DoughnutSeries visualizes its data points in doughnut segments.

Properties

The 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

Examples 1 and 2 demonstrates how to setup a DoughnutSeries using a RadPieChart.

Example 1: Defining the model and populating with data

public sealed partial class MainPage : Page 
{ 
    public MainPage() 
    { 
        this.InitializeComponent(); 
 
        this.mychart.Series[0].ItemsSource = CreateData(); 
    } 
 
    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; 
    } 
} 
 
public class Data 
{ 
    public double Value { get; set; } 
} 

Example 2: Defining the DoughnutSeries

<Grid xmlns:telerikChart="using:Telerik.UI.Xaml.Controls.Chart"V> 
    <telerikChart:RadPieChart x:Name="mychart" PaletteName="DefaultLight" > 
        <telerikChart:DoughnutSeries ShowLabels="True"> 
            <telerikChart:DoughnutSeries.ValueBinding> 
                <telerikChart:PropertyNameDataPointBinding PropertyName="Value"/> 
            </telerikChart:DoughnutSeries.ValueBinding> 
        </telerikChart:DoughnutSeries> 
    </telerikChart:RadPieChart> 
</Grid>
