We should just add
P.show(aspect_ratio="automatic")
etc., exactly as in Mathematica. The goal with 2d graphics in Sage
is that they at least support all options that Mathematica has.
Anyway, here is a function show11 that works exactly like show(...), but
it will always show with a 1:1 aspect ratio:
{{{
def show11(g, figsize=[5,4], **kwds):
for k in ['xmin', 'xmax', 'ymin', 'ymax']:
if kwds.has_key(k): g.__getattribute__(k)(kwds[k])
scale = (g.xmax() - g.xmin())/(g.ymax() - g.ymin())
g.show(figsize=[figsize[0], figsize[0]/scale], **kwds)
}}}
{{{
show11(plot(sin, 0, 5))
}}}
{{{
show11(circle((0,0), 2), xmin=-3, xmax=4)
}}}
This is now trac #1606:
