Smile in HTSeq example, pyplot

Hi All,

I am trying to run HTSeq with my data set and am using a script shown in HTSeq web site as a simple example. but just got error message in pyplot function in python. i am a very beginner of python.
is there anyone who ran this example successfully and can advise me what i am missing now here?


Thanx a lot in advance!

****
>>> from matplotlib import pyplot
>>> #import _tkagg
... #import Tkinter as Tk
...
>>> pyplot.plot(qualsum/nreads)
[<matplotlib.lines.Line2D object at 0x2f69cd0>]
>>> pyplot.show()
Exception in Tkinter callback
