Plotting charts in python cmd.Cmd

I am trying to plot some data in CLI. I am looking to plot multiple charts in separate window and it should not block CLI so that I can still give commands in CLI.

class CLI(cmd.Cmd):

    def __init__(self):
        super().__init__()

    def do_plot(self):
        # plot here


if __name__ == '__main__':
    CLI().cmdloop()

method 1: using matplotlib

I came to know that matplotlib is not thread safe.

method 2: pyqtgraph

I have asked a detail question here : https://forum.qt.io/topic/122033/running-multiple-plots-with-pyside2, still no solution.

Only solution I can think of now is that to write separate program and connect it with CLI using socket and share data. Is there any easy and efficient way to do it?
