matplotlib-devel Mailing List for matplotlib

Hi,
Trying to make a simple 2D line plots that show a grid as thin grey
lines, I noticed that the grid lines are on top of the data lines. I
think this issue may have come up a while ago.
Anyway, digging through axes.py, it looked like a simple solution was
to change axes.py line 358
- self._axisbelow =3D False # todo make me an rcparam
+ self._axisbelow =3D rcParams['axes.axisbelow']
and an rcParam to __init__py line 788:
 'axes.axisbelow' : [False, validate_bool], # put the axis below l=
ines
Then using
matplotlib.rc('axes', axisbelow=3DTrue)
worked as hoped. Is this a reasonable change? If so, can someone add thi=
s?
(for some reason I don't fully understand, I can't get svn to connect
to sourceforge from my main machine).
Thanks,
--Matt Newville

We seem to be repeatedly bitten by this type of bug in texmanager:
first with subprocess and now with the dvipng version check. I think
it would be worthwhile to refactor backend_ps and backend_agg to only
import the texmanager when needed. There is no reason a person with
usetex=False should fail.
I suggest something like (in backend_ps and backend_agg). 
class RendererPS:
 def __init__(self, blah):
 self.texmanager = None
 def get_texmanager(self):
 if self.texmanager is not None: return self.texmanager
 from matplotlib.texmanager import TexManager
 self.texmanager = TexManager()
and then only call get_texmanager if rcParams['text.usetex']. We
could also put this functionality in backend_bases.RendererBase
BTW, do we need renderer specific texmanagers. Would anything break
if we used module level texmanagers? Something tells me I've thought
about this before and concluded we needed renderer (ie figure) level
managers, but am now drawing a blank.

Thanks. I didn't mean to be terse or anything, but I just figured
someone would know what to fix off the top of their head.

Sorry about that, I didnt see that one coming.
This should be fixed in svn 2278.

SVN has a runtime error when checking for dvipng when I am not even
using it. Pretty much breaks everything right now.
