@Jason:
In Sage 4.8:
When adding a polygon to a plot, the aspect ratio of the polygon is
used. When adding a plot to a polygon, again, the aspect ratio of the
polygon is used. This is unexpected.
There was some discussion of plotting and aspect ratios last autumn:

Would it make sense / would it be possible to keep the default aspect
ratio of the first graph? My guess it that from the users point of
view using the aspect ration of the first graph would make a lot of
sense - at least when the polygon fits into the first graph.
I would find it strange if the sum of plots was noncommutative, at least
in terms of aspect ratio.
Right now, a numeric aspect ratio always overrides an 'automatic' aspect
ratio. Should we flip that behavior, so that 'automatic' always
overrides a numeric aspect ratio when two plots are added together? I
guess if I had something with automatic aspect ratio, I'd generally want
it to stay automatic, even if I added circles or parametric plots to it
(which both default to aspect ratio 1).
And it sounds like we ought to set polygon to default to 'automatic'
aspect ratio anyway, since it's causing so much confusion.
