Bug summary

TheXAxis /YAxis objects attached to anAxes haveget_transform andset_transform methods, but unlike other getters/setters, you can't get the value you set.

Code for reproduction

importmatplotlibasmplimportmatplotlib.pyplotasplt_,ax=plt.subplots()xfm=mpl.scale.LogTransform(10)ax.xaxis.set_transform(xfm)print(ax.xaxis.get_transform())

Actual outcome

IdentityTransform()

Expected outcome

LogTransform(base=10, nonpositive='clip')

Additional information

I'm not sure if this is really a bug or if it's just a confusing / rough edge. The scale/transform API is fairly cumbersome, but improving that situation is a big project. Is the transform you set withaxis.set_transform ever actually used? If not, then maybeset_transform should not exist (or it should raise if called)?
