Probably, what you are seeing is a graph of all zeros apart from the occasional 1 or 2, right?

You've missed out the 'gauge' option.  This is required since the OID you are monitoring is not a Counter, you want to graph its value directly (as opposed to a network 'total bytes' counter, where you want to graph the rate of change, which is the default with MRTG)
