i have added the below lines to the chart.py. I can see the chat created by matplotlib but i get this error: "RuntimeError: main thread is not in main loop."

import matplotlib as mpl
mpl.use('TKAgg')

When i replace the above line to the lines given below then it works without an error but no chart is shown:

import matplotlib as mpl
mpl.use('Agg')

the error is on the chart.py file on this command: plt.pause(0.01)

please reply.

This is a matplotlib issue, Be sure to run your program in a main loop.
