This is actually pretty difficult to implement because of the need for shipping RRDs to the client side. Permissions and the like get troublesome.

For the few instances where this is useful, I've never really seen the need. Just use the graph browser and set the date and time.

"zooming in" on anything other than the past 24 hours gives you a worthless mess of stair steps, so...

If I find an irregularity and want to take a closer look at it I have to fiddle around with the From and To Fields until I have the right time window.   Therefore I would really like the graphs in observium to be zoomable. E.g. by dragging a rectangle or maybe something like this: https://github.com/oetiker/RrdGraphJS [https://github.com/oetiker/RrdGraphJS]   Are there any plans for such an improvement?   Regards, Siegfried
