Polar Line Series

The PolarLineSeries are represented on the chart as data points connected with straight line segments.


The PolarLineSeries class inherits from the PolarPointSeries class - See the inherited properties.

  • Stroke (Brush): Gets or sets the Brush instance that defines the stroke of the Line shape that presents the series.
  • StrokeThickness (double): Gets or sets the thickness of the line used to present the series.
  • IsClosed (bool): Gets or sets a value indicating whether the Line shape will be closed (by connecting the last point to the first one). The default value is true.
  • AutoSortPoints (bool): Gets or sets a value indicating whether the data points associated with the series will be automatically sorted by their Angle property in ascending order. The default value is true.


Examples 1 and 2 demonstrate how to create a RadCartesianChart with a PolarLineSeries.

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 RadPolarChart and PolarLineSeries

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