continuous plotting with Tkinter

[Martin Blume]

I have a number-crunching application that spits out
a lot of numbers. Now I'd like to pipe this into a python
app and plot them using Tkinter, such as:
$ number_cruncher | myplot.py
But with Tkinter once I call Tkinter's mainloop() I
give up my control of the app and I can't continue to
read in data from stdin. Or can I? If so, how?

Regards
Martin

Maybe the simpler is to run the Tk mainloop in a separate thread.
You may have a look a candygram which gives a very simple to use
multi-thread semantics (ala Haskell) and is simpler to use than the
threading module.
