If I put in one OID that gives a result of 0 so that only one graph line
shows, it graphs pretty stable.  The funny thing is, when I create a
whole separate graph, but referencing the same OID, the newer graph
shows lots of spikes.  This graph almost resembles the CPU usage better
because when watching it in task manager, it jumps from a low percentage
<10 to high percentage > 80 almost constantly.  

If I leave the graph with the big spikes showing on and comment out the
other one, then the one with the spikes calms down.  What could be

Maybe it's doing this because of dual queries, for the same graph, to
the same oid? Try duplicating your graph with just one cpu oid per graph
and see if they are the same or not.
