Polar Area Series

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

Properties

PolarAreaSeries class inherits from the PolarLineSeries 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 RadCartesianChart with PolarAreaSeries.

Example 1: Defining the model and populating with data

public sealed partial class MainPage : Page 
{ 
    public MainPage() 
    { 
        this.InitializeComponent(); 
 
        double a = 0.5; 
        var b = (Math.PI / 180); 
        List<Data> data = new List<Data>(); 
        for (int i = 1; i < 5 * 360; i += 10) 
        { 
            data.Add(new Data() { Angle = i, Value = (a * Math.Cos(20 * i * b)) }); 
        } 
 
        this.polarChart.DataContext = data; 
    } 
} 
 
 
public class Data 
{ 
    public double Value { get; set; } 
 
    public double Angle { get; set; } 
} 

Example 2: Defining the RadPolarChart and PolarAreaSeries

<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:NumericalRadialAxis/> 
        </telerikChart:RadPolarChart.RadialAxis> 
 
        <telerikChart:PolarAreaSeries ItemsSource="{Binding}"> 
            <telerikChart:PolarAreaSeries.ValueBinding> 
                <telerikChart:PropertyNameDataPointBinding PropertyName="Value"/> 
            </telerikChart:PolarAreaSeries.ValueBinding> 
            <telerikChart:PolarAreaSeries.AngleBinding> 
                <telerikChart:PropertyNameDataPointBinding PropertyName="Angle"/> 
            </telerikChart:PolarAreaSeries.AngleBinding> 
        </telerikChart:PolarAreaSeries> 
    </telerikChart:RadPolarChart> 
</Grid>
