Thx all for your remarks,
I can't understand why this code works (when I use the timer method):

I think you forget to set the layout on your central widget.
self.main_widget.setLayout(vbl) # in your case

Thx Daniel I didn't know extend and it's more suitable for my program.
It doesn't change the problem of plotting, but thx again!

Hello everyone, I'm trying to plot live data extracting from remote
devices (here it's simulated by get_info1 and 2 the result is always
0.8 or 0.9
I can't understand why it doesnt plot the graph at the end of the
while loop. Does somebody has an idea?
