[yt-users] setting limits of the colorbar

[luigi at ita.uni-heidelberg.de]

Dear all,

I am currently trying to plot a 2D phase diagram (T vs rho). The plot  
is OK, but I have problems with setting the limits of the colorbar  
(where CellMassMsun is color-coded). Somehow, they are set  
automatically, which is bad, because I need to compare several plots  
of different datasets. The set_zlim command does not apparently affect  
the plot. I copy here my script, and I hope for some suggestions of  
yours.
Thanks in advance,

   Luigi
