To close a Python figure by a keyboard input, we can use plt.pause() method, an input, and close() method.
Steps
- Set the figure size and adjust the padding between and around the subplots.
- Create random t and y data points using numpy.
- Create a new figure or activate an existing figure using figure() method.
- Plot t and y data points using plot() method.
- Set the title of the plot.
- Redraw the current figure using draw() method.
- Run a true loop to pause the current figure.
- Take input from the user to go to the next statement.
- Use close() method to close the figure.
Example
import numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True t = np.arange(0.0, 2.0, 0.01) y = np.exp(-t) fig = plt.figure() plt.plot(t, y, lw=5, color='red') plt.title("$y=e^{-t}$") plt.draw() plt.pause(1) input("<Hit Enter>") plt.close(fig)
