Comment (by vbraun):
Its not just !RealLiteral that we have to worry about, somebody might
compute linewidth from some numerical formula and hand down elements of
other "real fields", like !RealField, !RealDoubleField, or
!RealIntervalField. I would suggest a more relaxed check, something like
{{{
try:
if v.parent() in Fields():
v = float(v)
except (AttributeError, TypeError):
pass
}}}
since I'm pretty sure that floating-point numbers are the only Sage field
that can be used as matplotlib parameters.
Also, it would be nice to save a copy of options and restore them after
the call to matplotlib.
