The problem here is when I say "go left" I mean "go right",
sometimes. :-)

To make the Z-buffer exactly like the window, you have to
set the resolution and colors *outside* the Z device. Otherwise,
you just set the resolution and colors to the defaults of
the Z device! You need something like this:

ncolors = !D.N_Colors - 1
xsize = !D.X_Size
ysize = !D.Y_Size

Set_Plot, 'Z'
Device, Set_Resolution=[xsize, ysize], Set_Colors=ncolors
Help, /Device

Cheers,

David
