===== Original message from John Hunter | Tue, 05 Jul 2005:
This was just a suggestion of an interface that could be implemented,
not one that exists. The interface would be
axvline(x=0, noupdate=True)
it is a good idea.
what about (in this case)
grid(x=[0], y=[0])
to control grid lines separate from xtic and ytic settings?
I agree -- could you add a feature request to the sourceforge site
with a description of the problem and a link to this thread?
will do.
