The examples finance_work on the web site
http://matplotlib.sourceforge.net/screenshots.html#finance_work2 loads
financial data from a CSV file. It uses a function load_quotes
defined in the helper.py module
http://matplotlib.sourceforge.net/screenshots/finance_work2.py
http://matplotlib.sourceforge.net/screenshots/helpers.py
The data files for this example are found in
http://matplotlib.sourceforge.net/screenshots/data/
The downside is that this is a fairly sophisticated example that may
not be that easy to parse if you are getting started with
python/matplotlib, so hopefully someone on this list can provide a
simpler one for you.
Hope this helps,
John
