Not certain that a graph with all zeros on the Y axis is much of an
improvement :-)
It rounded 0.033 to 0.0, I didn't think that would happen.
I believe if you also use "-L 4" to specify how many digits RRD may
use in the Y axis, it will display correctly.
I can't run any tests right now, so I might be wrong here, but -X 0 -L
4 seems to be what you're looking for. If that doesn't work please
read the manual carefully (that link from my previous e-mail), I'm
sure it's not a complicated issue.
