Polar Spline Series

Overview

The PolarSplineSeries are represented on the chart as data points connected with smooth line segments as shown on the image below:

Properties

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

Example

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

  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:PolarSplineSeries ItemsSource="{Binding}">
            <telerikChart:PolarSplineSeries.ValueBinding>
                <telerikChart:PropertyNameDataPointBinding PropertyName="Value"/>
            </telerikChart:PolarSplineSeries.ValueBinding>
            <telerikChart:PolarSplineSeries.AngleBinding>
                <telerikChart:PropertyNameDataPointBinding PropertyName="Angle"/>
            </telerikChart:PolarSplineSeries.AngleBinding>
        </telerikChart:PolarSplineSeries>
    </telerikChart:RadPolarChart>
