FAIL: test_scatter_matrix_axis (pandas.tests.test_graphics_others.TestDataFramePlots) in 0.18.1 with py27

[neirbowj]

When run alone, test_scatter_matrix_axis passes. When run together with the rest of TestDataFramePlots, it fails.

I cannot test with py34 because matplotlib is not available on FreeBSD under py3k.

Code Sample, a copy-pastable example if possible

% nosetests-2.7 pandas.tests.test_graphics_others:TestDataFramePlots.test_scatter_matrix_axis

Thanks. Haven't been able to reproduce yet, but I'm going to clean up that testing module anyway to catch all those userwarnings and fix the matplotlib deprecation warning. Hopefully I'll figure out what's going wrong.
