Hey Mike,
Instead, it would make more sense to make use of the clipping
algorithm already in matplotlib (and implemented in fast C++) that will
actually splice the line segments at the boundary. I've attached a patch
for this.
Good call. Our main clipping issue that still needs to be
A python module of mine could draw a plot, and so imports from matplotlib.
Actually, plotting is part of the module test that is in
if __name__==__main__
But this kills my job trying to run non-interactively.
This is IMO rather nasty behavior. matplotlib should not try to open the
display
You need to set your backend to a non-GUI one (such as Agg) if you want
to run without a display. This FAQ answer may be helpful:

Thanks for the info, but I still think this is rude behavior for a python
module, and believe it would be a good thing to fix it.

Use case is I have a module that does digital design. If run as main, it
has a little test that does a plot. The plot is supposed to use a gui and
display.
But if not run as main, there is no plot, and maybe no display.
I had:
if __name__ == __main__:
from matplotlib.pyplot import *
but
It's not that simple. In order to get text metrics and start laying out
a plot for some backends (notably Gtk and Wx), the GUI framework needs
to be imported. Sure, we could import them on demand once the user
actually starts doing stuff, but that would require sprinkling the code
with
We've had users run into the same problem (and have a similar reaction). At
least on our end, there was a key assumption that users were making about how a
plotting system worked. They expected to be able to do something like this:
... plot stuff here

P.savefig( plot.png )

The recent nasty import behavior thread motivated me to post an issue I've

I am not a usetex user, but in testing mpl on a linux box I got a new
error for dvipng. I hadn't seen this on this box before (it used to
work there) but I am not suspecting an mpl bug at this point, rather a
bug on the system. I don't really know, but others have reported
similar dvipng bugs
