Hi all,

I'm = still a bit stuck with this probleme of polar annotation.
Let = me present the problem in a different way.

I've = got the center of my circle, its radius and even some points on the = circle.
Actually, I'd like to annotate these points (red = crosses in the joined picture).
How would you do = that?

My best try gave me the green = numbers.
