Matplotlib plot window is black

Question

I recently started studying python and matplotlib. The problem I face is that I always get a black window as a plot output.

See simple code below.

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


x = np.arange(0, 5, 0.1)
y = np.sin(x)

#plot the x and y and you are supposed to see a sine curve
plt.plot(x, y)

pylab.show()

I get the same result executing code samples from matplotlib pages. Does anyone have any idea where this comes from and how to overcome this?

I'm using the Operating system Linux Mint.

Actually the use of pylab is discouraged, so try plt.show() instead, maybe it'll help? matplotlib.org/faq/… — Oleg Medvedyev

Can you try to get matplotlib.get_backend() in python shell? You may miss some libraries. See pyimagesearch.com/2015/08/24/… — Oleg Medvedyev

I executed code in python shell and it works, the problem comes executing code in python editors. I worked with two different editors.

Best regards
