[rrd-users] RRDtool lying about data values

I'm using using the following software to monitor link utilization on
network devices:

MRTG 2.9.17-3
RRDtool 1.0.45

I had started using MRTG alone, then converted to rrdtool and 14all.cgi. I
also dropped my polling interval from 5 minutes to 1. When I look at the
graphs, the values listed under them don't mesh with the data points on
the curve. As one can see in the example:
http://home1.gte.net/jodih/graph.png. The maximum out is stated to be
113.028Mbps, while the graph clearly shows it to be more about 150Mbps.

Is there some sort of math error here?

Thanks in advance,
