RRD zoom issues
list Stef Coene
Hi, Since the upgrade to 4.3, we have issues when zooming in on the graphs. See the attached screen shots. It looks like the max and min values are calculated wrong when zooming in. This messes up the scaling of the graph. Does anyone sees the same behavior? Rrdtool version: 1.4.7-2ubuntu5 Xymon version: 4.3.17 Stef

Hi, I also noted that https://www.xymon.com/ has the same issues. So it is not related to my specific setup. Stef

Workaround: when you zoom-in, make sure you select *vertically* the whole graphic, as well as the horizontal section you're interested in. I'm not sure when this behaviour started, but I'm pretty sure it wasn't like this in the olden days. Never bothered to investigate it though :-) ~f

Nice catch! Thx for the work around. I also found out that you can remove upper and lower from the url. Stef

A better fix is editing file zoom.js and comment out line 688: // newURL = newURL + "&upper=" + newGraphTop + "&lower=" + newGraphBottom; Stef

I've seen this problem in the past, with an old version of Hobbit when used with the Chrome browser, whereas there were no problems with IE. Have you tried with a different browser? The xymon.com website works fine for me, in both IE and Chrome. J

It's not the zoom itself. But the new zoom scripts also use the upper and lower points as zoom points. So it not only zooms the X time scale, but also the Y max and min values. Stef

And you don't want this feature?
