A generic monday is not necessarily the average of four consecutive mondays. 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?

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). HTH Alex _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
