Here's an example of how to create a RadCartesianChart with SplineAreaSeries.

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

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

    List<Data> data = new List<Data>();
    data.Add(new Data() { Category = "Apples", Value = 5 });
    data.Add(new Data() { Category = "Oranges", Value = 9 });
    data.Add(new Data() { Category = "Pineaples", Value = 8 });
    this.splineAreaSeries.DataContext = data;
  3. Finally, create the chart using XAML.

    <telerikChart:RadCartesianChart x:Name="splineAreaSeries" PaletteName="DefaultLight">
        <telerikChart:SplineAreaSeries ItemsSource="{Binding}">
                <telerikChart:PropertyNameDataPointBinding PropertyName="Category"/>
                <telerikChart:PropertyNameDataPointBinding PropertyName="Value"/>
