[matplotlib-devel] colormaps in pcolor

[Jon P. <jw...@ps...>]

John,

loving matplotlib - thx.

Was using pcolor today but needed a gray colormap rather than jet. Made 
my own version (see attached) using a class Colormap with attribute 
color (which can be set to 'jet'). Seemed a bit more adaptable and more 
like matlab. I linked ColormapJet back to this class so that other 
people's code wont break (hopefully ;) ). Probably worth allowing users 
to supply there own as an array too, but I didn't have time to do that 
today.

On a different topic slightly, I wonder if it would be worth having a 
plot type based on image widgets. For large arrays pcolor is still very 
slow under gtk. Maybe either using image widgets for pcolor itself or 
having a different plot type (like matlabs 'image' or 'imagesc').

all the best
Jon
