# Radar Charts

## Content



A **Radar** chart is a variation of a Polar chart. A Radar chart draws the y value in each data set along a radar line. If the data has n unique points, then the chart plane is divided into n equal angle segments, and a radar line is drawn (representing each point) at 360/n degree increments. By default, the radar line representing the first point is drawn vertically (at 90 degrees).

The labels for radar chart can be set using [ChartData.ItemNames](/componentone/api/wpf/online-chart/dotnet-framework-api/C1.WPF.C1Chart.4.6.2/C1.WPF.C1Chart.ChartData.ItemNames.html) property. These labels are located at end of each radial line.

**Setting the Starting Angle**

The [PolarRadarOptions.SetStartingAngle](/componentone/api/wpf/online-chart/dotnet-framework-api/C1.WPF.C1Chart.4.6.2/C1.WPF.C1Chart.PolarRadarOptions.SetStartingAngle.html) attached property of the [PolarRadarOptions](/componentone/api/wpf/online-chart/dotnet-framework-api/C1.WPF.C1Chart.4.6.2/C1.WPF.C1Chart.PolarRadarOptions.html) class sets the starting angle for Radar charts. The Start Angle allows you to rotate the chart clockwise. For example, if you set the **SetStartingAngle** property to 90, then the chart will rotate clockwise by 90 degrees.

The following image represents the Radar chart when you set **ChartType** property to **Radar**.
