Range Radar Area

May 28, 2021
4 minutes to read

Range Radar Area belongs to the Radar Series group. To display this series, use the RadarRangeAreaSeries2D class.

Range Radar Area shows data as a filled area on a circular grid. This series requires two values for each series point to specify range limits.

Series Type Characteristics

The table below lists the main characteristics of a series:

Feature	Value
Series View	RadarRangeAreaSeries2D
Diagram	RadarDiagram2D
Number of arguments per series point	1
Number of values per series point	2

Note

Refer to the Series Type Compatibility article for information about compatible series.

Specify Series Data

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:

XAML

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

Bind to a Data Source

To populate Radar Range Area Series with data from a data source, specify the following properties:

XAML

<dxc:RadarRangeAreaSeries2D ...
    DataSource="{Binding Data}" 
    ArgumentDataMember="Argument"
    ValueDataMember="Value"
    Value2DataMember="Value2">
     ...
