Spherical harmonics in spherical coordinates

hi,

I am trying to draw spherical harmonics, implemented as an TF2 object, using the option "surf1 sph", but I do not get the desired results, even after reading the messages in:

http://root.cern.ch/root/roottalk/roottalk09/0340.html

There seems to be a problem with the "SPH" option or I have missed some points in the documentation. I would be grateful if you could point out a way
to correct this problem.

The macro is attached. I am running it after loading the Mathmore library in the interpreter with:

gSystem->Load("libMathMore")

Best regards, Marcelo

ps. I am sorry i posted this problem in the wrong place before.
