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.
