Radar Spline Series

Updated on Mar 26, 2026

The RadarSplineSeries are represented on the chart as data points connected with smooth line segments.

Properties

RadarSplineSeries class inherits from the RadarLineSeries class -

See the inherited properties.

Example

Examples 1 and 2 show how to create a RadCartesianChart with a RadarSplineSeries.

Example 1: Defining the model and populating with data

C#

public sealed partial class MainPage : Page
{
	public MainPage()
	{
		this.InitializeComponent();

		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;
	}
}

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

	public double Category { get; set; }
}

Example 2: Defining the RadPolarChart and RadarSplineSeries

XAML

<Grid xmlns:telerikChart="using:Telerik.UI.Xaml.Controls.Chart">
	<telerikChart:RadPolarChart x:Name="polarChart">
		<telerikChart:RadPolarChart.PolarAxis>
			<telerikChart:PolarAxis/>
		</telerikChart:RadPolarChart.PolarAxis>
		<telerikChart:RadPolarChart.RadialAxis>
			<telerikChart:CategoricalRadialAxis />
		</telerikChart:RadPolarChart.RadialAxis>

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