One of my first attempts at a contribution to matplotlib three years ago was related to this. It was in reply to a similar question on list, and I wrote a patch, but never saw it through to inclusion because it wasn't something I needed. http://www.mail-archive.com/matplotlib-users@lists.sourceforge.net/msg09216.html I think it's a helpful starting point, as I include a discussion on the limitation of mpl colormaps there. -- Paul Ivanov 314 address only used for lists, off-list direct email at: http://pirsquared.org | GPG/PGP key id: 0x0F3E28F7
