The Radar chart type is a circular chart that is used primarily as a data comparison tool. It is sometimes called a spider chart or a star chart. The plot area can also be displayed as a polygon.
Unlike most other chart types, the Radar chart type uses the circumference of the chart as the X axis.
3D is not supported when the AreaDrawingStyle custom attribute is set to Circle (the default value). When the AreaDrawingStyle custom attribute is set to Polygon, only the Area3DStyle.Enable3D property has any effect on this chart. If you set Area3DStyle.Enable3D to true, the drawing style of the area background changes to give the appearance of looking down on a 3D cone.
