import sys
import numpy as np
import matplotlib.pyplot as plt

def on_press(event):
    print('press', event.key)
    if event.key == 'x':
        visible = xl.get_visible()
        xl.set_visible(not visible)

# Fixing random state for reproducibility

fig, ax = plt.subplots()

ax.plot(np.random.rand(12), np.random.rand(12), 'go')
xl = ax.set_xlabel('easy come, easy go')
ax.set_title('Press a key')
