Spline Area Series

With a SplineAreaSeries the data points are connected with smooth line segments and the area enclosed by the line and the coordinate axis may be optionally stroked and/or filled.

SplineAreaSeries class inherits from the AreaSeries class -See the inherited properties.

Example

Examples 1, 2 and 3 show how to create a RadCartesianChart with a SplineAreaSeries.

Example 1: Defining the model

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

Example 2: Populating with data

public MainPage() 
{ 
    this.InitializeComponent(); 
    List<Data> data = new List<Data>(); 
    data.Add(new Data() { Category = "Apples", Value = 5 }); 
    data.Add(new Data() { Category = "Oranges", Value = 9 }); 
    data.Add(new Data() { Category = "Pineaples", Value = 8 }); 
 
    this.splineAreaSeries.DataContext = data; 
} 

Example 3: Defining the RadCartesianChart and SplineAreaSeries

<Grid xmlns:telerikChart="using:Telerik.UI.Xaml.Controls.Chart"> 
    <telerikChart:RadCartesianChart x:Name="splineAreaSeries" PaletteName="DefaultLight"> 
        <telerikChart:RadCartesianChart.VerticalAxis> 
            <telerikChart:LinearAxis/> 
        </telerikChart:RadCartesianChart.VerticalAxis> 
        <telerikChart:RadCartesianChart.HorizontalAxis> 
            <telerikChart:CategoricalAxis/> 
        </telerikChart:RadCartesianChart.HorizontalAxis> 
 
        <telerikChart:SplineAreaSeries ItemsSource="{Binding}"> 
            <telerikChart:SplineAreaSeries.CategoryBinding> 
                <telerikChart:PropertyNameDataPointBinding PropertyName="Category"/> 
            </telerikChart:SplineAreaSeries.CategoryBinding> 
            <telerikChart:SplineAreaSeries.ValueBinding> 
                <telerikChart:PropertyNameDataPointBinding PropertyName="Value"/> 
            </telerikChart:SplineAreaSeries.ValueBinding> 
        </telerikChart:SplineAreaSeries> 
    </telerikChart:RadCartesianChart> 
</Grid>
