It seems odd to me that there should be a get_scale but no set_scale. I'm also mildly bothered by the fact that methods outside of Axis have to call the "private" methods. I don't have any suggestions here, just airing my thoughts...

Thanks for doing this @tacaswell .

Yeah -- marking as 1.3.x, but I want to think on this for a bit. I can't help thinking there might be a better way.

Currently all of the calls to _set_scale are in methods of axes object methods, so it's not that bad.

My thoughts on this are colored by c++ style friend relationships. I don't see how an axis is useful outside of an axes or an axes is useful without an axis so the has-a and is-a relationships get fuzzy.

Sorry about the spelling errors, did not realize the spell checker was not working.

I copied the import of mplDeprecation out of axes.py, should I make a PR to fix that too?

@tacaswell Yes please. That must be a left over when mplDeprecation was in the init.py file.
