Radar Line Series

Updated on Mar 26, 2026

The RadarLineSeries are represented on the chart as data points connected with straight line segments.

Properties

RadarLineSeries class inherits from the RadarPointSeries class -

See the inherited properties.

• Stroke (Brush): Gets or sets the Brush instance that defines the stroke of the Line shape that presents the series.
• StrokeThickness (double): Gets or sets the thickness of the line used to present the series.
• IsClosed (bool): Gets or sets a value indicating whether the Line shape will be closed (connecting the last point to the first one). The default value is true.
• AutoSortPoints (bool): Gets or sets a value indicating whether the data points associated with the series will be automatically sorted by their Category property in ascending order. The default value is true.

Example

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

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 RadarLineSeries

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