We support following options for Position and Rotate for data label in polar coordinate:
- For Rotate, add <Radial> and <Angular> to dropdown list.
- <Radial> is direction from polar center to data point.
- <Angular> is perpendicular to <Radial> and in clockwise direction.
- For Position, add Angular Outer and Angular Inner to dropdown list.
- Angular Outer means the point on label bounding box which is closest to the center of polar should be on the outer of data point
- Angular Inner means the point on label bounding box which is farthest to the center of polar should be on the inner of data point
- If angular outer or inner is selected, offset should not be horizontal and vertical. We should use Angular Offset(degree) and Radial Offset(% of font height)
