[yt-users] EPS.single_plot() interface

It looks like it's failing when it's making the axes, which might happen
when the ymin and ymax are the same. Could you print out the _xrange
and _yrange variables in the axis_box_yt() function in eps_writer.py
just before the call to self.axis_box()?
Does the eps_writer work for non-yt calls?
http://paste.yt-project.org/show/4032/
Does eps_writer work for normal slices and projections?
You're doing the correct procedure to patch your version. It doesn't
hurt to rerun the install script, but it's unnecessary. You could have
run "python setup.py install" from the yt-hg/ directory instead.
I hope we can pinpoint the cause of the error soon!
Cheers,
John
