subplot does not work in svn

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,

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.

I think this is a valid key in rcParams.

Doesn't the error trigger a full traceback that shows where it is coming from?

I am still getting this problem. Here is an ipython traceback of a very simple plot:

In [1]: from pylab import *

In [2]: plot([3,45,6],[7,9,2])

The thing is, I deleted my entire ~/.matplotlib directory, hoping to start clean. Where does matplotlib get its info when a .matplotlibrc is not present in my home directory?

Thanks

Chris, try

xmode verbose

in ipython right before running your code. 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,
