Radar Spline Area Series

When using RadarSplineAreaSeries the data points are connected with smooth line segments that enclose an area that may be optionally stroked and/or filled.


RadarSplineAreaSeries class inherits from the RadarAreaSeries class - See the inherited properties.


Examples 1 and 2 show how to create a RadCartesianChart using a RadarSplineAreaSeries.

Example 1: Defining the model and populating with data

public sealed partial class MainPage : Page 
    public MainPage() 
        List<Data> data = new List<Data>(); 
        for (double i = 1; i < 30; i += 1) 
            data.Add(new Data() { Category = i, Value = ((0.7) * Math.Cos(20 * i)) }); 
        this.polarChart.DataContext = data; 
public class Data 
    public double Value { get; set; } 
    public double Category { get; set; } 

Example 2: Defining the RadPolarChart and RadarSplineAreaSeries

<Grid xmlns:telerikChart="using:Telerik.UI.Xaml.Controls.Chart"> 
    <telerikChart:RadPolarChart x:Name="polarChart"> 
            <telerikChart:CategoricalRadialAxis /> 
        <telerikChart:RadarSplineAreaSeries ItemsSource="{Binding}"> 
                <telerikChart:PropertyNameDataPointBinding PropertyName="Value"/> 
                <telerikChart:PropertyNameDataPointBinding PropertyName="Category"/>
