Polar Line Series

The PolarLineSeries are represented on the chart as data points connected with straight line segments.

Properties

The PolarLineSeries class inherits from the PolarPointSeries class - See the inherited properties.

• Stroke (Brush): Gets or sets the Brush instance that defines the stroke of the Line shape that presents the series.
• StrokeThickness (double): Gets or sets the thickness of the line used to present the series.
• IsClosed (bool): Gets or sets a value indicating whether the Line shape will be closed (by connecting the last point to the first one). The default value is true.
• AutoSortPoints (bool): Gets or sets a value indicating whether the data points associated with the series will be automatically sorted by their Angle property in ascending order. The default value is true.

Example

Examples 1 and 2 demonstrate how to create a RadCartesianChart with a PolarLineSeries.

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 PolarLineSeries

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