I am trying to make a wind rose diagram.
I took into consideration these 2 posts
I am attaching two cases.One with background image which has the knots range and one which has the percentage range.
So, my problems are:
1) In the knots version, I can't assign the length of the radius to the according knots.
2) In the percent version, I can't express the percentage and I don't know how to align the background image to fit that percentage.
Any ideas ?
