Matplotlib plot window is black

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)

enter image description here

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 Linx Mint.

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