===== Original message from Mark Bakker | Fri, 1 Jul 2005:
Detailed instructions for adding a color map seem to be given in the user
manual on page 61. Did you try that?
can anyone explain this format to me?
_cool_data = {'red': ((0., 0., 0.), (1.0, 1.0, 1.0)),
'green': ((0., 1., 1.), (1.0, 0., 0.)),
'blue': ((0., 1., 1.), (1.0, 1., 1.))}
