Is the polygon halves of the circle or what? If not, then MapServer cannot cut 
the
circle in half for you. Your best bet would be to use a couple of point layers. 
One to
draw the whole circle and another to draw just half of it. Then you can label 
each
half. Here's an example image and mapfile:

Great! thank you for all the effort


taking the offset into account correctly. Probably not a big deal in your case 
since I
imagine the circles are the main attraction in the map.
Actually they are used to display additional information for a polygon layer. This polygon layer represents parts of a city. For every part of the city there different values apply. Think about the maximum height which is allowed for buildings and the maximum height on which a gutter may be placed. The circles get important if you want information about a layer(the people are used to have this information on their map's so it will be a hard job talking them out of this idea ;) ) 



I got a bit carried away with the drop shadows and outlines. Kinda wanted to see
what was possible...

Thank you for the work and i can now make the thing working!
Below i have pased your code, so all future searches on this topic can find the information also in the mail-archive. (next lines are owned by Steve Lime <[EMAIL PROTECTED]>)
