hehe, not yet. I am learning by trial & error, google and skimming
this tutorial. So far I have read about 5% of that tutorial ;-))

aha! so it should be () instead of (1,2)

yes, the first call is blocking because of pylab.show().
I found it by trial and error :) In fact I don't know why
pylab.show() is called, because even without it the figure() appears
on the screen.

I made it more apparent in my second diff with livePlotInit parameter.

there's in fact a lot to fix. The biggest problem for me is using
TMP_data. That *sum(..) line is plain magic for me, and I totally
don't understand it. And currently my code works only for uniax.py
but I couldn't get it to work with any other script that does
plotting.

Maybe you could, erm, rewrite that magic line into something longer
that is easier to read and find bugs?

 
> mtTkinter can be added locally to yade, no problem.

I would like to know how you added it lcoally :) I will read your commits.
Especially that part in which I had to use root access to
edit /usr/lib/pymodules/python2.6/matplotlib/backends/tkagg.py


btw, that is its homepage:

best regards
