1. 6 months ago I started the first rrd. 2. Today the second rrd starts. 3. To get a nice graph, I eliminate the "*UNKNOWN*"s. This will lead to an average calculation for over the last 12 months (if the graphs goes over 12 months), so I do a second CDEF. 4. This leads me to the situation (I guess it's like that, if not I'd be glad) that the average calculation starts today. I would like it to start 6 months ago, when the first rrd started. My guess comes from the behaviour of the aggregated graph, if things are different, I'd be fine. Could you tell ? Thanks a lot in advance and also for the help you gave already !
