I am new to matplotlib and I am trying to get started with animation
library.There is an example here for a simple strip
chart:https://matplotlib.org/examples/animation/strip_chart_demo.htmlI tried
to use this example in a thread. I created a simple *threading.Thread*
class, and in it's* run() *method, called:ani = animation.FuncAnimation(fig,
scope.update, emitter, interval=10,True)plt.show()here is class:class
graph(threading.Thread): def __init__(self, feeder):
threading.Thread.__init__(self) self.fig, self.ax = plt.subplots()
self.scope = Scope(self.ax) self.feeder=feeder
self.running=True def run(self): while self.running:
ani = animation.FuncAnimation(self.fig, self.scope.update,
self.feeder.emit_ch1(), interval=1, blit=True) plt.show()
but when I start this thread, it never shows the windows. Isn't this right
usage?
def run(self):
while self.running:
ani = animation.FuncAnimation(self.fig, self.scope.update,
self.feeder.emit_ch1(), interval=1, blit=True)
plt.show()

main thread is owning the GUI. My Python installation runs Tkinter version
: 8.5 and this happens with Tkinter. I ran the same code on another machine
which used another GUI framework(not sure what was it) and it went well. So
I guess something is wrong with Tkinter.

GUI frameworks tend to require they be on the main thread. Which backend
/ gui framework are you using here?
In general you will have to arrange things so that the main thread owns
the GUI windows + plotting and the child threads own the computation.
