Now that I think about it, if you really just want 12
colors, the code probably looks more like this:

cgLoadCT, 33, NColors=12
cgImage, BytScl(C, TOP=11), /Axes, Position=[0.125,0.125,0.95,0.8], $
/Window
cgColorbar, Range=[min(C),max(C)], /Discrete, $
Postion=[0.125,0.915,0.955,0.95],$
Charsize=1.00, Format='(F0.4)', NColors=12, /AddCmd
cgControl, Output='tt.png'

Cheers,

David
