[Matplotlib-users] unexpected exception

Hi!
I'm a newbie of matplotlib, and I'm trying to plot a set of data... but I
got blocked...

$ cat matplotliberr.py
#!/usr/bin/env python

# dummy data to plot
from datetime import date, timedelta
from random import randint
x = [ date.today() + timedelta(i) for i in range(10) ]
y = [ randint(0, i) for i in range(10) ]

from matplotlib import pyplot
pyplot.fill(x, y) # no problem using pyplot.plot(x, y)
pyplot.show()
$ ./matplotliberr.py
