# 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:PolarAxis/>

<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>
