That's not giving us anything. It doesn't draw a picture of the subscribe frequency, nor does it provide a better view of the number of subscribers. In fact, the graphs would be quite flat and uninteresting. The first version on murphy had them, since the rrdtool in potato was too old. As an example check out these two graphs of debian-announce. http://people.debian.org/~joey/stuff/debian-announce-distabs-month.png http://people.debian.org/~joey/stuff/debian-announce-distabs-normal-month.png Regards, Joey -- Let's call it an accidental feature. --Larry Wall Please always Cc to me when replying to me on the lists.

Hi again. On Fri, Sep 21, 2001, Martin Schulze wrote: [zeropoint or not - that's the question] That's not giving us anything. It doesn't draw a picture of the subscribe frequency, nor does it provide a better view of the number of subscribers. Well, it _does_ draw a picture of subscribe frequency, related to all the people already subscribed. If you want a picture of just subscribe frequency, than make that: With the zero-point in the middle, and subscriptions add and unsubscribes substract from there. A graph for a statistic is worth nothing if it doesn't have the zero point in it. First unit statistics lesson. In fact, the graphs would be quite flat and uninteresting. The first But it would be a real graph. version on murphy had them, since the rrdtool in potato was too old.

So the still offer a false view of the state. I don't exactly know whom you want to impress with those false graphs or what you want to be able to see from it - but the current state seems to miss that, IMHO. Just my thoughts, nothing personal, as you should know. Go on like you like, personally I see it in this way quite useless.

A graph for a statistic is worth nothing if it doesn't have the zero point in it. First unit statistics lesson. 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
