python plot doesn't display a window on ubuntu [duplicate]

Question

When I run this simple code:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4])
plt.ylabel('some numbers')
plt.show()

I don't get any window. I tried to save it into file and it works, but I want to display window with plot on screen.

I'm using python version 2.7.3. And I'm working on Ubuntu.

How can I show the window/plot?

Have you installed numpy? matplotlib requires numpy version 1.4 or later. You could get the installation steps from here
