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.
The document includes the following sections:
This diagram can only contain the following compatible series types:
Refer to the Series Type Compatibility document to learn more about series compatibility.
The axis of arguments in the Radar diagram is represented as a circular axis. This axis is available with the RadarDiagram2D.AxisX property.
Note
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:

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;
}
' Cast Diagram to the RadarDiagram2D type.
Dim diagram As RadarDiagram2D = TryCast(chart.Diagram, RadarDiagram2D)
If diagram IsNot Nothing Then
' Access the diagram's options.
diagram.ShapeStyle = CircularDiagramShapeStyle.Polygon
End If
