[rrd-users] Reversed values

[Marc T. Kaplan]

Andy,


   You are right, I was not sure if it was a specific issue or general given
RRDtools. I posted parts of the script you referenced in your reply below. I
have run different values and tried reading up on RRD to understand it
better, given the specific database I am trying to create. This is more or
less a project that I was thrown into head first and I am still trying to
understand everything related to RRD. If you see anything specific regarding
the data below please tell me what might be wrong.
