2D Radar Diagram

  • 3 minutes to read

The 2D Radar Diagram is used to display data as a circular graph. A radar chart consists of a sequence of spokes dividing the diagram into equiangular sectors, where an each spoke represents one of the variables.

How to Create a Chart with a Radar Diagram

The axis of arguments in the Radar diagram is represented as a circular axis. This axis is available with the RadarDiagram2D.AxisX property.



Note that radar diagram axes do not support additional elements such as constant lines, axis titles, and strips.

The following markup demonstrates how to create a chart with the Radar diagram:

    <!-- Radar diagram's settings. -->
    <dxc:RadarDiagram2D RotationDirection="Counterclockwise" 
        <!-- X-axis settings. --> 
        <!-- Y-axis settings. -->
        <!-- The Radar series settings. -->
        <dxc:RadarPointSeries2D x:Name="series">
            <dxc:SeriesPoint Argument="1/1/2017" Value="2"/>
            <dxc:SeriesPoint Argument="2/1/2017" Value="2"/>
            <dxc:SeriesPoint Argument="3/1/2017" Value="3"/>
            <dxc:SeriesPoint Argument="4/1/2017" Value="5"/>
            <dxc:SeriesPoint Argument="5/1/2017" Value="8"/>
            <dxc:SeriesPoint Argument="6/1/2017" Value="11"/>
            <dxc:SeriesPoint Argument="7/1/2017" Value="13"/>
            <dxc:SeriesPoint Argument="8/1/2017" Value="13"/>
            <dxc:SeriesPoint Argument="9/1/2017" Value="11"/>
            <dxc:SeriesPoint Argument="10/1/2017" Value="8"/>
            <dxc:SeriesPoint Argument="11/1/2017" Value="5"/>
            <dxc:SeriesPoint Argument="12/1/2017" Value="3"/>

The following table lists classes and properties that are used in the markup:

Class or Property Description
ChartControl The Chart control.
RadarDiagram2D The 2D Radar Diagram.
CircularDiagram2D.RotationDirection Specifies the direction in which the diagram's argument axis is drawn.
CircularDiagram2D.ShapeStyle Specifies the diagram's shape style.
CircularDiagram2D.DomainBrush Specifies the brush used to draw the diagram's area.
CircularDiagram2D.DomainBorderBrush Specifies the brush used to draw the diagram's area border.
CircularDiagram2D.StartAngle Specifies an angle of deflection from vertical to define an axis origin of coordinates.
CircularDiagram2D.LabelsResolveOverlappingMinIndent Specifies the minimum gap between two adjacent series point labels.
RadarDiagram2D.AxisX Gets or sets the x-axis settings.
RadarAxisX2D The radar diagram's circular arguments axis.
RadarDiagram2D.AxisY Gets or sets the y-axis settings.
RadarAxisY2D The radar diagram's circular axis of values.
RadarLineSeries2D The Radar Line series.
Series.DisplayName Specifies a series display name.
SeriesPoint The series point.
SeriesPoint.Argument Specifies the series point's argument.
SeriesPoint.Value Specifies the series point's value.

Refer to the code below to access the Radar diagram's settings at runtime:

// Cast Diagram to the RadarDiagram2D type. 
RadarDiagram2D diagram = chart.Diagram as RadarDiagram2D;
if (diagram != null) {
    // Access the diagram's options. 
    diagram.ShapeStyle = CircularDiagramShapeStyle.Polygon;
