For my real time graphing script, I was hunting down a bug that wasn’t allowing the matplotlib animation function.
It turns out we needed to delay in the while 1 loop to allow the animation function to fully finish.

plot = plotter(queue, save_figas)
ani = plot.ani
try:
while True:
plt.pause(0.1) # <-- KEY POINT need small pause to allow animation to update
pass
except KeyboardInterrupt:
print("interrrupted by keyboard")Code can be seen at https://github.com/smaroukis/realtime-plotter/. Here is an overview:
