Not sure why you are having trouble.
htdocs/screenshots/finance_work2.py is working for me with matplotlib
CVS, 0.83.2 and 0.83

Can you test the finance_work2.py example so at least we're working
with the same code? And since there were a few releases in the 0.83
series, it might help if you post the result of running your code with
the --verbose-helpful example so I know which bugfix release you are
working with. Here's what I get:

peds-pc311:~/python/projects/htdocs/screenshots> python
finance_work2.py -dTkAgg --verbose-helpful
matplotlib data path /usr/share/matplotlib
loaded rc file
matplotlib version 0.83
