The STAR-chart in PROC GCHART does not draw lines from the origin to the points on the enclosing circle. I did not find an option to include such lines. Therefore I am trying to draw these radial lines with Annotate. However, so far I was not able to pick up the location of the origin (center) nor the radius of the enclosing circle. Any suggestion how to do that?
Are you just looking for how to include the lines (e.g., the noconnect option) or combining the two? If it is the former, take a look at: http://support.sas.com/documentation/cdl/en/graphref/63022/HTML/default/viewer.htm#gr13n15-ex.htm
No, that is not what I want.
Below is the first picture of that article. I added the lines that I want in RED. The run from the center to each of the midpoint markers on the enclosing circle. In addition to the lines I also want to add tickmarks to the lines, but I suppose that when I am able to create the lines adding the tickmarks is not a major problem.
That would be an option in some situations, but the challenge remains: how do I get the right co-ordinates for the various points in a STAR-chart. Although drawin radial lines is probably not very relevant to PIE-charts, the general problem how to position annotate elements in PIE- and START-charts remain.
proc gchart and annotate are definitely not amongst my specialties, thus you may want to simply disregard what I have to say regarding your problem. I came awfully close to producing what you want, but in a rather odd and incomplete way. However, as you haven't received an answer yet, I figure I may at least share the method .. as forceful and incomplete as it is. Hopefully, minimally, you might be able to use it to help discover what you are missing.

I see what you do. And yes this may work, provided that you keep the graphics environment equal, in order to keep the size and position of the two charts that you are stacking identical. But what about adding other elements to a PIE or START chart. I assume there must be some method in the Annotate facility to find the right co-ordinates of the center and the radius of the enclosing circle?!
Erik, I will have to leave your question for someone who is more familiar with SAS/graph and annotate than I am. I produced my pseudo solution to your problem this morning, but didn't post it as I was hoping that some "real" graph experts my provide the "real" answer.
Unfortunately, you may have to wait until after the holidays, which is why I decided to share my feeble attempt.
hi ... the big problem with using annotate to modify a star chart is that the data coordinate system cannot be used, so you'd have to figure out the locations of anything that has to be tweaked based on percentages of output area and that'll vary from chart to chart
so, Art's overlay solution is a lot easier than annotate (but pretty limited as to what you can accomplish)
