Weird y-axis in plot

I'm finding some really weird behavior in matplotlib that I just can't figure out.

When I plot out the following short script:

>>> from pylab import *
>>> y = [-48.0694,-48.0754,-48.0772,-48.0781,-48.0782,-48.0781,
                -48.0772,-48.0720]
>>> plot(y)
>>> savefig('bs.png')

I get a y-axis that goes from -10 to 0, instead of -48.0782 - -48.0694. And in the upper left hand corner of the plot I see the string "x1e-3-4.8069e1".

I'm running python 2.3.5 on Mac OS X 10.4.2. Matplotlib 0.82.

Any hints?
