Then RRD Tool is not for you. RRD is specifically designed to allow storage of values using consolidation to allow for efficient storage of data over long timescales but at reduced resolution. Somewhere in the docs it talks about how data is entered, and it specifically converts everything to fit the sampling periods defined for the database. Eg, if you set the sample rate at 5 minutes, but one of your samples was late (at 6 minutes) then rrdtool would put 5/6ths of the value into the last sample bucket, and keep the other 1/6th for the next - or at least that's how I interpret it as working. For what you want, you would be better off with one of the other graphing/plotting tools that are out there (but whose names don't come to mind as I haven't used any of them).
