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.

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.

Marc, "Reversed values" is not the norm :) It would help to send along the commands you are using the create the graph, and, perhaps, the commands that you are using to store the data. /andy
