How to set timeout to pyplot.show() in Matplotlib?

To set timeout to pyplot.show() in Matplotlib, we can take the following steps −

• Set the figure size and adjust the padding between and around the subplots.
• Create a new backend-specific subclass of '.Timer'.
• Add a callback function that will be called whenever one of the plt.close() properties changes.
• Plot a list of data points.
• Start the timer.
• To display the figure, use show() method.

Example

import matplotlib.pyplot as plt

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

fig = plt.figure()

# set the timer interval 5000 milliseconds
timer = fig.canvas.new_timer(interval = 5000)
timer.add_callback(plt.close)

plt.plot([1,2,3,4,5])
plt.ylabel('Y-axis Data')

timer.start()

plt.show()

Output

The window will close automatically after 5 seconds, as we have set the timer interval at 5000 milliseconds.
