Properties

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

Example

Here's an example of how to create a RadCartesianChart using RadarSplineAreaSeries:

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

    public class Data
    {
        public double Value { get; set; }
    
        public double Category { get; set; }
    }
    
  2. Then create the sample data:

    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;
    
  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:RadarAreaSeries ItemsSource="{Binding}">
            <telerikChart:RadarAreaSeries.ValueBinding>
                <telerikChart:PropertyNameDataPointBinding PropertyName="Value"/>
            </telerikChart:RadarAreaSeries.ValueBinding>
            <telerikChart:RadarAreaSeries.CategoryBinding>
                <telerikChart:PropertyNameDataPointBinding PropertyName="Category"/>
            </telerikChart:RadarAreaSeries.CategoryBinding>
        </telerikChart:RadarAreaSeries>
    </telerikChart:RadPolarChart>
