Hi Janek, this is a great feature, I tried several times and it never
worked properly. If you notices, the first call to plot.plot() is
blocking (till you close those plots), while the next ones are not; I
suspect that this is exactly the issue.

A problem is that matplotlib has several backends (Tk, Gtk, Wx) and they
sould be all supported -- let's see. Another problem is that a a LOT of
code is duplicated, and it is code that is not easy to read and can be
buggy.

Thanks for your contribution, I will try to fix that and merge plot with
liveplot etc. so that the code is readable.

mtTkinter can be added locally to yade, no problem.

Cheers, Vaclav
