multiprocessing show matplotlib plot

Question

I\'m trying to open up multiple plots but I ran into a few problems. When I tried to create plots using threading, python would first open a number of windows, then close al

Answer 1

The following code produces two figures as desired.

import matplotlib.pyplot as plt
import numpy as np

import multiprocessing
#multiprocessing.freeze_support() # <- may be required on windows

def plot(datax, datay, name):
    x = datax
    y = datay**2
    plt.scatter(x, y, label=name)
    plt.legend()
    plt.show()

def multiP():
    for i in range(2):
        p = multiprocessing.Process(target=plot, args=(i, i, i))
        p.start()

if __name__ == "__main__": 
    input('Value: ') 
    multiP()
