Been awhile since I did anything with rrd or mrtg but could it be that
you have selected the wrong type for the value being represented?  I
seem to recall a type that allowed for values to be reset to zero
(counter rolls over).  You may have a type set that is looking for
increasing values only.  From your brief description it sounds like the
counters may be rolling over and cacti is having trouble figuring this
out.  You need to have a data type that is cumulative so when/if the
counter roles over to zero the graphs will continue to show the expected

Change the data type used to the correct type and it should work.
