Scatter Spline Series

Updated on Mar 26, 2026

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

ScatterSplineSeries class inherits from the ScatterLineSeries class - See the inherited properties.

Example

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

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 ScatterSplineSeries

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

RadCartesianChart with a ScatterSplineSeries

WinUI RadChart Scatter Spline 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.
