Plotting live pie-chart using matplotlib pyplot

Question

Code:

import matplotlib.pyplot as plt
from time import sleep
for i in range(100):
    plt.pie([100-i,i])
    sleep(1)
    plt.show()

Problem with my code:

• Whenever the values of plt.pie() changes and the pie chart are plotted then execution of for loop seems to be halted and I have to close the pie chart window to resume to the execution of for loop.

What I want to do:

• plt.pie() display live changes in its values without halting for loop's execution.

thank you.

Answer 1

add plt.close() to your for-loop

import matplotlib.pyplot as plt
from time import sleep
for i in range(100):
    plt.pie([100-i,i])
    sleep(1)
    plt.show()
    plt.close()
