Rubbish. The correct lesson is to learn to always look at the scale before drawing conclusions. Once you've learnt that, graphs without a zero point have a place: they show more details. There is certainly no law against them. Zero-point graphs would make it easier to compare the different graphs, certainly, if that's what one wants to do. Personally the thing that jars me is the inconsistency: some graphs are scaled so that their vertical variation is more-or-less full range, whilst others take only a small percentage of the vertical height. But there is a limit to the amount of time it's fun to spent meddling with rrdtool options... Jules
