[Matplotlib-users] colorbrewer colormaps

[Vidar G. <vid...@37...>]

i would like to add colorbrewer colormaps to matplotlib,
at least for my personal use, but i would like to do this
properly so that this can be used by others.

ColorBrewer:
http://www.personal.psu.edu/faculty/c/a/cab38/ColorBrewerBeta2.html

any hints on where to start? start with the cm.py module?
extend cm.py or create a stand-alone one?

the ColorBrewer palettes could be addressed by something
like one of the following, i guess?:

   cmap=cm.colorbrewer.PuBuGn
   cmap=colorbrewer.PuBuGn

the colorbrewer palettes are specified by 3 to 9 rgb colors,
each interpolated differently, how many of these points would
be preferred in a matplotlib module?

...or even all of them, assuming 5seq as a default
(when using the above):

   cmap=cm.colorbrewer.PuBuGn.3seq
   cmap=cm.colorbrewer.PuBuGn.9seq
