Does y2 have to be greater than y1 in Range or DrawFrame?

Rene,
    Thank you for the answer to my previous question; it worked
beautifully.

    My question concerns ploting (theta,phi) points on a rectangular
projection. I would like the top to have theta=0 and the bottom to have
theta = 180. If I do a 

      p2->DrawFrame(0,180,360,0);
 
I end up with a frame that has y-range from 179 to 181. If I do a 

      p2->DrawFrame(0,0,360,180);

everything works, but is upside down.

Thanks again in advance,

Chris
