The patch at the end of this post *should* render the scaling factor above the
xaxis labels on the top axis. It should, but it doesn't. Instead, it renders
the scaling factor overlapping the tick labels on the top axis. I don't
understand this behavior, considering the scaling factor is properly rendered
if the bottom axis is the one that is labeled.
As for overlapping with twinx and twiny, I don't know how best to proceed
here. The offset_text's parent axis would have to inspect its own ticklabels
as well as the ticklabels of the OTHER axis, and based on their extent, find
a new location for the offset_text. This is starting to get in the realm of
requiring a layout manager in order to implement properly.
I'm preparing for a professional meeting next week (anyone else going to MRS
in Boston?) and don't have time to continue working on this. Perhaps the
patch is enough to get someone else pointed in the right direction.
