What's the opinion about adding footnotes to plots, that can
optionally be turned off?
e.g. the first plot here is an influence plot
http://www.statsmodels.org/dev/examples/notebooks/generated/regression_plots.html
The plot doesn't mention what the sizes of the disks/circles represent.
Also, the y-axis could use either one of two definitions (external or internal).
BTW: reading that notebook again, I think it's very "nice" (written by
Skipper a long time ago)
some plots could benefit from a face lift, but I'm just fixing bugs.
