Radar Area Series

When using a RadarAreaSeries the data points are connected with straight line segments that enclose an area that may be optionally stroked and/or filled.

Properties

RadarAreaSeries class inherits from the RadarLineSeries class - See the inherited properties.

• Fill (Brush): Gets or sets the Brush that defines the interior of the area.

Example

Examples 1 and 2 show how to create a RadPolarChart with a RadarAreaSeries.

Example 1: Defining the model and populating with data

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 RadarAreaSeries

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