Polar Series Views
The series of Polar view types are used to display data as a circular graph. These view types are similar to Radar Series Views, but display values on the basis of angles (from 0 to 360 degrees). Note that although these charts normally have a circular shape, they can also be displayed as a polygon. The following image represents several polar charts.
Below is the list of all polar charts currently available in the WinForms Chart Control.
