[Matplotlib-users] changing labeling of axes

[Slavin, Jonathan]

Hi Ben,

The issue with that is that I want to retain the logarithmic binning. If I
change the xscale/yscale to log with the binning as set up now, then it
will try to scale the log values logarithmically.  So I still want the axes
to be scaled in the same way, I just want the labeling of the axes to be
different.  Is that clear?
