Check that either
1) This is a true counter, and it is definitely increasing over time, or
2) This is a gauge, and you have the gauge option set in the MRTG

If you have a gauge counter (eg: free space on your filesystem) and you
don't set Option[]:gauge, then you will get this sort of effect.

If you have a counter (eg: total network packets) and the counter is not
increasing, then you will get this effect.
