RadCartesianChart visualizes AreaSeries as an area on the chart that is enclosed by the coordinate axes and straight line segments that connect the data points represented by these series. The AreaSeries extend CategoricalStrokedSeries, so they are also CategoricalSeries and require one CategoricalAxis and one NumricalAxis.


  • Fill : gets or sets the fill of the AreaSeries.
  • Stroke : changes the color used to draw lines.
  • StrokeThickness : changes the width of the lines.


Here is an example of how to create a basic RadCartesianChart with AreaSeries in xaml:

    <telerikChart:AreaSeries ItemsSource="{Binding CategoricalData}">
        <telerikChart:PropertyNameDataPointBinding PropertyName="Value"/>
        <telerikChart:PropertyNameDataPointBinding PropertyName="Category"/>



Here is an example of how to create a RadCartesianChart with AreaSeries in code:

var chart = new RadCartesianChart
    HorizontalAxis = new CategoricalAxis(),
    VerticalAxis = new NumericalAxis(),
    BindingContext = new CategoricalViewModel()

var series = new AreaSeries();
series.SetBinding(AreaSeries.ItemsSourceProperty, new Binding("CategoricalData"));   
series.ValueBinding = new PropertyNameDataPointBinding("Value");
series.CategoryBinding = new PropertyNameDataPointBinding("Category");


Here is the sample data:

public class CategoricalData
    public object Category { get; set; }
    public double Value { get; set; }

public class CategoricalViewModel
    private static Random random = new Random();
    private static string[] categories = new string[] { "Greenings", "Perfecto", "NearBy", "Family", "Fresh" };

    public CategoricalViewModel()
        this.CategoricalData = GetCategoricalData();

    public ObservableCollection<CategoricalData> CategoricalData { get; set; }

    public static ObservableCollection<CategoricalData> GetCategoricalData()
        var data = new ObservableCollection<CategoricalData>();
        for (int i = 0; i < categories.Length; i++)
            data.Add(new CategoricalData() { Value = random.Next(50, 100), Category = categories[i] });

        return data;

And here is the result:

Basic AreaSeries

Here we have some customizations:

var series = new AreaSeries { Stroke = new Color(0.6, 0.6, 0.9), StrokeThickness = 5, Fill = new Color(0.8, 0.8, 1) };
