[Matplotlib-users] matplotlib WX and Qt4Agg backends

[TheLonelyStar <na...@lo...>]

Hi,

I have installed matplotlib with the "WX" and the "Qt4Agg" backend. Both
have problems:

with WX backend, I can plot something. But when I close the window and try
to plot again, nothing happens (no window opens).

with Qt4Agg I can plot something. But when I close the window and try to
plot again, I get the error I posted below.

Can something be done about one if these problems?

Thanks!
Nathan
