How to display a plot in fullscreen

Question

i am trying to display a plot but in fullscreen. This is my code :

import numpy as np
import pylab as plt
a = np.array([1,2,3,4])
b = np.array([1,2,3,4])
plt.plot(a,b,'.')
plt.show()

But the problem is : this does not display with the fullscreen. Any ideas to solve this ? Thank you.

Answer 1

The code provided in the accepted answer will maximize the figure, but won't display it in fullscreen mode.

If you are keeping a reference to the figure, this is how you can toggle fullscreen mode:

import matplotlib.pyplot as plt

fig = plt.figure()
fig.canvas.manager.full_screen_toggle() # toggle fullscreen mode
fig.show()

alternatively, if you're not keeping a reference:

import matplotlib.pyplot as plt

plt.figure()
plt.get_current_fig_manager().full_screen_toggle() # toggle fullscreen mode
plt.show()

To toggle fullscreen mode using your keyboard, simply press f or Ctrl+f.

If you also want to remove tool and status bar, with the full_screen_toggle mode you can prove:

fig, ax = plt.subplots() 
plt.rcParams['toolbar'] = 'None' # Remove tool bar (upper)
fig.canvas.window().statusBar().setVisible(False) # Remove status bar (bottom)

manager = plt.get_current_fig_manager()
manager.full_screen_toggle()
