You can provide a dot-separated path to the module and function, eg. 
(this is assuming the test is installed):
nosetests matplotlib.tests.test_simplification:test_clipping

Mike,
What is the easiest way to run a single test? I want to work on one 
failure at at time.

I suspect I'm the culprit. I will look into it.

I'm noticing that SVN r8269 is failing a great number of regression 
tests -- with pretty major things like the number of digits in the 
formatter being different. The buildbot seems to be getting the same 
failures I am, but I don't see any buildbot e-mails since Wednesday. 
Does anyone know the source of these errors? It seems to have to do 
with changes to the formatters.
Mike

Thanks. I can confirm this with today's SVN. I'm looking into the cause.
Mike

This is a known bug which is fixed in svn. You need to set
path.simplify : False
in your matplotlibrc http://matplotlib.sourceforge.net/users/customizing.html
