Showing Available Color Maps

Question

How do you show what color maps are available?

Answer

The show command will do this. Note that this method is attached to a VCS canvas object so you have to first initialize a canvas:

>>> import vcs
>>> v = vcs.init()
>>> v.show('colormap')

(   1):                AMIP                 ASD             b_and_w
(   4):                cmap            dc_table             default

I'm still trying to figure out exactly what each of the colormap names mean; if you find out, please let me know. If you want to see what these predefined color maps look like, go here.
