I have a multi series (multi-level) pie chart. Its actually a representation of a 24 hour clock (24 wedges). I want to put a label at the 12:00, 3:00, 6:00, and 9:00 positions at the very outside edge (radius) of the pie chart. I am guessing I would have to put the pie chart in to a canvas so that I can put the labels at absolute positions????? Also, how do I find out the x/y coordinate of the origin of the circle (the point at the middle of the pie chart)? I didnt see anything obvious in the documentation. There has to be something I am missing???
maybe I should ask the question another way: is there a way to get at the geometric primitives of the pie chart graphics to find out the center radius?
