I have just updated to a matplotlib build from SVN, and now all my subplots generate errors: (Pdb) rows Out[3]: 2 (Pdb) columns Out[3]: 2 (Pdb) num Out[3]: 1 (Pdb) subplot(rows, columns, num) *** KeyError: 'axes.formatter.limits' I really dont know why this is happening, so I would appreciate any assistance. Thanks, Chris -- Chris Fonnesbeck + Atlanta, GA + http://trichech.us
Chris, I suspect it is a problem with your matplotlibrc file; you could try stripping it down to bare minimum, as in the svn root directory. Another possibility is that your update is somehow incomplete or scrambled with an earlier installation. If that doesn't work, try making a minimal script that illustrates the problem. examples/newscalarformatter_demo.py works fine, so I don't think the basic subplot mechanism is broken.

This will make the traceback dump even more detail, which may help John and his evil minions track down your little critter even faster. Cheers, f

Chris,
My guess is that you have some combination of 0.87.7 and svn; the
traceback says 0.87.7, and the KeyError is because of an addition to
rcParams since 0.87.7.
Try this:
In [1]:import matplotlib
In [2]:matplotlib.rcParams
Out[2]:
{'axes.axisbelow': False,
'axes.edgecolor': 'k',
'axes.facecolor': 'w',
'axes.formatter.limits': (-7, 7),
'axes.grid': False,
'axes.hold': True,
etc. etc.
If you don't see the axes.formatter.limits key then your __init__.py is
not from svn. Maybe the thing to do is delete all versions and traces
of matplotlib from your system and then re-download and install.
