Polar Bar Graph
The Polar Bar graph or series is used to represent data as bars (line segment) in the
polar coordinate system. It has two mandatory series
and Distance. The data in these two components specifies the
positions of the end points of the bars. All bars share the common start point: the
origin of the polar coordinate system. The series also has an optional component called LabelMember
whose data may be used as the mark labels for the bars.
The Pen and the Points properties determine the appearance of the
bars and the end points, respectively.
