If Steve's suggestion is not what you are looking for, have a look at SHIFT (in the rrdtool graph manual). > Is this something rrdtool can do? At the moment I cant see how I could as > all the x axis values would be different as they are time based Indeed. And that time can be SHIFTed :) >From memory: four data sources (pointing at the same source), shift by 0,1,2 or 3 times 604800 seconds (1 week) should give you the data. Now use AVG (see the RPN docs).
