What does your .SH script look like?
Maybe things have changed in the later versions of MRTG (i've been out of it
for a while) and it is now assuming zero for the second number, however if
you look at your graphs, there is a blue line down at the bottom.

goto http://people.ee.ethz.ch/~oetiker/webtools/mrtg/reference.html and
search for External Monitoring Scripts.
