No, there is not.  Original numbers are not kept.  They are normalized
and they are used to compute a rate.  Only these normalized rates are

However, it is possible to enter rates into a new database.  If you
want to tell RRDtool "do not touch these numbers" then you have to:
1) use GAUGE
2) enter at exact the right time

This way the numbers are already rates (so: no computations) and the
effect of normalizing is reduced to zero (the time is right).

Then, when you're finished, you can change the counter type from GAUGE
to COUNTER (or whatever else you want).

"Exactly the right time" depends on the step time of the database.  It
is the time displayed in the output of fetch.
