Polar Spline Area Series

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


PolarSplineAreaSeries class inherits from the PolarAreaSeries class - See the inherited properties.


Examples 1 an 2 show how to create a RadCartesianChart with a PolarSplineAreaSeries.

Example 1: Defining the model and populating with data

public sealed partial class MainPage : Page 
    public MainPage() 
        double a = 0.5; 
        var b = (Math.PI / 180); 
        List<Data> data = new List<Data>(); 
        for (int i = 1; i < 5 * 360; i += 10) 
            data.Add(new Data() { Angle = i, Value = (a * Math.Cos(20 * i * b)) }); 
        this.polarChart.DataContext = data; 
public class Data 
    public double Value { get; set; } 
    public double Angle { get; set; } 

Example 2: Defining the model RadPolarChart and PolarSplineAreaSeries

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