Matplotlib not displaying figures
Question: This must be a really basic question: I am trying to use Matplotlib. Here's
the basic example from the
[documentation](http://matplotlib.sourceforge.net/api/pyplot_api.html).

    
    
    import numpy as np
    import matplotlib.pyplot as plt
    x = np.arange(0,5,0.1)
    y = np.sin(x)
    plt.plot(x,y)
    

I have tried this in `ipython`, `bpython` and the default interpreter (Ubuntu
10.10, 64 bit) and all I get are messages like:

    
    
    [<matplotlib.lines.Line2D object at 0x3f14a90>]
    

What am I doing wrong?


Answer: You're missing `plt.show()` to order matplotlib to show a window with the
graph.
