Y axis scaling bug

I found a bug in the Y-axis scaling. See the attached PS

Darren Dale posted a small fix related to ticking for exponentially
formatted data to the users list today - you may want to see if that
helps.

Otherwise, if you can send me a tarball which has a script and some
data so I can replicate the bug, I'll take a look. These bugs are
easier to fix if you have something to test against.

No, the latest CVS still shows the bug.

Attached is the data (FITS) file and the following are the commands that I use to plot the data. You may need to download the pyfits module to access the file.

>>> import pyfits
>>> from matplotlib.matlab import *
>>> fits = pyfits.open('C05302010011alif4ttagfcal.fit')
>>> data = fits[1].data.field
>>> plot(data('wave'), data('flux'))
[<matplotlib.lines.Line2D instance at 0x40da5c4c>]
>>> show()

Thanks for taking a look at this.
