Polar Chart
To render a polar series, use seriesType as Polar.
Draw Types
Polar drawType property is used to change the series plotting type to line, column, area, range column, spline, scatter, stacking area and stacking column. The default value of drawType is Line.
Line
To render a line draw type, use series DrawType as Line. IsClosed property specifies whether to join start and end point of a line series used in polar chart to form a closed path. Default value of isClosed is true.
