RadarRangeAreaSeries2D Class

The Radar Range Area series.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v20.1.dll

Declaration

public class RadarRangeAreaSeries2D :
    CircularRangeAreaSeries2D
Public Class RadarRangeAreaSeries2D
    Inherits CircularRangeAreaSeries2D

Remarks

This series displays data as a filled area on a circular grid and requires two values for each series point.

You can add Radar Range Area Series to a diagram of the RadarDiagram2D type.

Manually Add Points

You can populate the Series.Points collection manually. Note that the Series.Points is a content property. You can declare points in XAML directly after the RadarRangeAreaSeries2D declaration. You do not need to wrap them in the opening and closing Series.Points tags.

Specify the following properties for each series point:

<dxc:RadarRangeAreaSeries2D...>
   <dxc:SeriesPoint
       Argument="01/01/2001"
       Value="6"
       dxc:RadarRangeAreaSeries2D.Value2="2" />
   ...
</dxc:RadarRangeAreaSeries2D>
