I think this has come up previously but I don't recall seeing a response...but how hard would it be to have the Zoom Graph function set the graph max to more accurately reflect the height of the block you select...ie, if I have a low load and I select a max height of around .2 when I drag my box, could the max on the new zoom be .2 instead of 1.0?
First of all, it would require that you're using version 1.2.x of the RRDtool
library. I guess it's safe to upgrade now, but back when I was putting the zoom stuff together, rrdtool 1.2 wasn't quite stable.
rrdtool 1.0 simply doesn't provide the information about the value range on the y-axis that is needed to implement the zoom. Tobi Oetiker who maintains
the rrdtool library added this in 1.2 at my suggestion :-)
I'll look at reviving some old code I had to implement this. It requires some changes to both the hobbitgraph CGI and the zoom.js javascript code.
