How to switch matplotlib digits visibility?

Is there a way I can make the matplotlib shape disappear and reappear in response to some kind of event? (i.e. keystroke)

I tried using fig.set_visible(False), but for me it does nothing.

A simple code example:

import matplotlib
import matplotlib.pyplot as plt

fig=matplotlib.pyplot.figure(figsize=(10, 10))

# Some other code will go here

def toggle_plot():
  # This function is called by a keypress to hide/show the figure
  fig.set_visible(not fig.get_visible()) # This doesn't work for me

plt.show()

The reason I'm trying to do this is because I have a bunch of plots / animations on the diagram that show the result of the simulation, but displaying them all the time slows down my computer. Any ideas?

You have to call plt.draw()to actually create any changes. This should work:

def toggle_plot():
  # This function is called by a keypress to hide/show the figure
  fig.set_visible(not fig.get_visible())
  plt.draw()

You can use the Toplevel () widget from the tkinter library along with the matplotlib backend.

Here is a complete example:

from tkinter import *
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg

fig,(ax) = plt.subplots()
x = np.linspace(0, 2 * np.pi)
y = np.transpose([np.sin(x)])
ax.plot(y)

graph = Toplevel()
canvas = FigureCanvasTkAgg(fig,master=graph)
canvas.get_tk_widget().grid()
canvas.show()

import pdb; pdb.set_trace()

Vocation:

graph.withdraw()

hide the chart and:

graph.deiconify()

will display it again.
