Scatter Spline Area Series

Updated on Mar 26, 2026

When using the ScatterSplineAreaSeries the data points are connected with straight line segments and the area enclosed by the line and the coordinate axis may be optionally stroked and/or filled.

The ScatterSplineAreaSeries class inherits from the ScatterAreaSeries class - See the inherited properties.

Example

The following example shows how to create a RadCartesianChart with a ScatterSplineAreaSeries.

Defining the model

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

	public double Value { get; set; }
}

Populating with data

public MainPage()
{
	this.InitializeComponent();

	List<Data> sampleData = new List<Data>
	{
		new Data() { Category = 2, Value = 3 },
		new Data() { Category = 3, Value = 4 },
		new Data() { Category = 4, Value = 5 },
		new Data() { Category = 5, Value = 6 },
		new Data() { Category = 6, Value = 5 },
		new Data() { Category = 7, Value = 4 },
		new Data() { Category = 8, Value = 3 },
		new Data() { Category = 9, Value = 4 },
		new Data() { Category = 10, Value = 5 },
		new Data() { Category = 11, Value = 4 },
		new Data() { Category = 12, Value = 3 },
		new Data() { Category = 13, Value = 2 },
		new Data() { Category = 14, Value = 1 }
	};

	this.radCartesianChart.DataContext = sampleData;
}

Defining the RadCartesianChart and ScatterSplineAreaSeries

XAML

<Grid xmlns:telerikChart="using:Telerik.UI.Xaml.Controls.Chart">
	<telerikChart:RadCartesianChart x:Name="radCartesianChart">
		<telerikChart:RadCartesianChart.VerticalAxis>
			<telerikChart:LinearAxis/>
		</telerikChart:RadCartesianChart.VerticalAxis>
		<telerikChart:RadCartesianChart.HorizontalAxis>
			<telerikChart:LinearAxis/>
		</telerikChart:RadCartesianChart.HorizontalAxis>

		<telerikChart:ScatterSplineAreaSeries ItemsSource="{Binding}">
			<telerikChart:ScatterSplineAreaSeries.XValueBinding>
				<telerikChart:PropertyNameDataPointBinding PropertyName="Category"/>
			</telerikChart:ScatterSplineAreaSeries.XValueBinding>
			<telerikChart:ScatterSplineAreaSeries.YValueBinding>
				<telerikChart:PropertyNameDataPointBinding PropertyName="Value"/>
			</telerikChart:ScatterSplineAreaSeries.YValueBinding>
		</telerikChart:ScatterSplineAreaSeries>
	</telerikChart:RadCartesianChart>
</Grid>

RadCartesianChart with a ScatterSplineAreaSeries

WinUI RadChart Scatter Spline Area Series

The spline-type series provides a property that allows you to control the tension of the spline. To do so, set the SplineTension property. The tension works with relative values between 0 and 1. The defualt tension is set to 0.5.
