Polar Area Series

Overview

When using PolarAreaSeries the data points are connected with straight line segments that enclose an area that may be optionally stroked and/or filled as shown on the image below:

Properties

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

• Fill (Brush): Gets or sets the Brush that defines the interior of the area.

Example

Here's an example of how to create a RadCartesianChart with PolarAreaSeries:

1. First, create a class for the sample data:

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

2. Then create the sample data:

   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;
   

3. Finally, create the chart in XAML.

   <telerikChart:RadPolarChart x:Name="polarChart">
       <telerikChart:RadPolarChart.PolarAxis>
           <telerikChart:PolarAxis/>
       </telerikChart:RadPolarChart.PolarAxis>
       <telerikChart:RadPolarChart.RadialAxis>
           <telerikChart:NumericalRadialAxis/>
       </telerikChart:RadPolarChart.RadialAxis>
   
           <telerikChart:PolarAreaSeries ItemsSource="{Binding}">
           <telerikChart:PolarAreaSeries.ValueBinding>
                   <telerikChart:PropertyNameDataPointBinding PropertyName="Value"/>
               </telerikChart:PolarAreaSeries.ValueBinding>
           <telerikChart:PolarAreaSeries.AngleBinding>
                   <telerikChart:PropertyNameDataPointBinding PropertyName="Angle"/>
               </telerikChart:PolarAreaSeries.AngleBinding>
           </telerikChart:PolarAreaSeries>
   </telerikChart:RadPolarChart>
