#1295: Confusing and/or inaccurate labels on probability plot ('stats.probplot')
axes

Comment(by jmpolom):
Correct, those are the only two line changes. I was obviously just using
probplot for normal probability plots, and I did forget to investigate
what it does for non-normal plots. From what a gentleman with a PhD in
statistics told me, 'Order Statistic Medians' is not the correct label for
that axis in any case. I can cross check with him and get some references
to cite in the docstring. I know the NIST stats tutorial lists that as the
axis label, but I honestly haven't seen it anywhere else.
Perhaps we could look into doing a distribution dependent label? Typically
for normal plots, the axis on which they're plotted reads 'Normal Scores'
or something to that effect. Similar labels for other distributions
shouldn't be too hard.
The docstring could use updating as it wasn't clear from it what exactly
was on that axis. I read the source to figure it out. Probably a good idea
to let people know what the thing does without having to find out where
their OS happens to install SciPy :)
