[rrd-users] Is there a way to filter out bad data in a derive counter?

I have this RRD where I feed Wh values, and I just found out that the
counter value I get is sometimes erroneous (i.e. huge jump forwards or
I could pre-treat the data with a script to somehow find and remove the
bad data points, but I think RRD already had some kind of built in way
of doing that, although I can't quite put my finger on it right now.
Does someone have a pointer they can share?
Otherwise or in addition, I suppose I can hand edit the bad data in the
RRD, but that can't be simple, especially if it's recorded potentially
in multiple resolution buckets, correct?
