If all your values are positive (and you are sure of it), you could use the SymmetricalLogScale It uses log scale for large values (both positive and negative), and linear for small ones.
http://matplotlib.sourceforge.net/devel/add_new_projection.html I believe there is a way to do it without going symetrical (ie, only defined for positive values), but I am unable to find it.
