You need a couple other files as well - should have mentioned this in
the finance_work file...

Save the following in the same dir as finance_work.py

http://matplotlib.sourceforge.net/screenshots/helpers.py

http://matplotlib.sourceforge.net/screenshots/msft_nasdaq_d.csv

http://matplotlib.sourceforge.net/screenshots/__init__.py

You'll also probably want to add a call to the function show at the
end of the file if you want to display the results in a GUI window.

Good luck!

Hi John,

thanks for your answer, but I already have a problem while launching the
script :

Fatal Python error: PyEval_RestoreThread: NULL tstate
abnormal program termination

After a lot of response from google impossible to find the problem...

If you have some clue, I take !

Thanks

This kind of error is almost always caused by an incompatibility in
the GUI environment you are using and the backend you have chosen.
The default backend is set in the configuration file - see
http://matplotlib.sf.net/.matplotlibrc. See also
http://matplotlib.sourceforge.net/faq.html#FREEZE and
http://matplotlib.sourceforge.net/backends.html for general
information on this problem.

If you are running matplotlib from an IDE such as IDLE and you want to
use the tkagg backend (a typical configuration for win32 users), it is
recommended that you launch idle with -n. Unfortunately, there was an
error in matplotlib/backends/backend_tkagg.py in the 'show' function
in the 0.60.2 release. If this indeed is your configuration, try
editing this file and commenting out the line

Tk.mainloop()

in the show function and relaunching idle with -n.

The safest way to test/play/experiment with matplotlib is to launch
your script from the command shell, choosing the backend with the -d
flag, as in

C:> python myscript.py -dTkAgg

as described on http://matplotlib.sourceforge.net/backends.html. Once
you have matplotlib configured to your satisfaction from the shell,
you can refine your backend and IDE choice following the guidelines in
the links above.

Hope this helps,
John Hunter
