[Matplotlib-users] logarithmic colormaps for imshow

[John [H2O] <was...@gm...>]

In mpl_toolkits.basemap there is a module cm.

I have been using the cm.s3pcpn colormap for some plots which require
logarithmic coloring. The cm.s3pcpn_l colormap is also available (apparently
a linear version).

I wanted to know whether there were any other logarithmic colormaps
available... for example, I would like to use gist_rainbow or gist_ncar, but
I haven't been able to so far using the example below. Suggestions?


The relevant section of code is here:

dmn = 0.00001
dmx = 1000000
logspace = 10.**np.linspace(dmn, dmx, 100) 
clevs = logspace
im = m.imshow(topodat,cmap=cm.s3pcpn,vmin=clevs[0],vmax=clevs[-1])
