[rrd-users] graph lines differ from actual values

[John Stile]

I am using rrdtool, libdbi, and mysql to chart thermal data.

I noticed the lines are sometimes a little higher than the actual data
being plotted, and I would like them to match.

Is there something I can change to make the graphed data match the
actual data?
