Looking on trac, you'd think this was fixed, but in fact it took me
four seconds to come up with an example where it's still an issue:
sage: G = posets.IntegerPartitions(5).hasse_diagram()
sage: G.show()
The "axes_pad" solution is not a viable one, as changing vertex size
and proportions can change the amount of padding needed. Someone needs
to solve this right, and we need a way of keeping it from regressing!
So I guess my second issue would be to have doctests which produce
plots to actually verify that they're not getting garbage.
I agree that the fix in 4.3.2(?) is a bandaid that solves most common cases.
I think maybe a call to axis('tight') at the right place might be the
right thing to do. See http://sagenb.org/home/pub/1595/ for the effect.
Thanks,
Jason
