Dragging/zooming graphs broken

[Roger]

Hello.

Something seems to have broken in regards to dragging and zooming various graphs.
When you first click on a graph everything looks fine but as soon as you try to drag it left/right it “corrupts” and if you try to zoom it just blanks out.

Quick example:

Output of ./validate.php:

Hmm, can you show the graph urls it is trying? (web dev console network)

I definitely tested that before, maybe some other fixes broke it…

[Roger]

Sure.

/graph?type=device_processor&device=645&from=1793855765&to=10425065&height=683&width=2515
For example errors with HTTP 500

Example when trying to scroll the graph left and right:

Edit:
This only seems to happen when scrolling a graph that is set to “last x hours/weeks” etc as timespan if you understand what I mean.

If the timespan is set to YYYY-MM-DD HH:MM to YYYY-MM-DD(+1) HH:MM for example it seems to work fine.

Thanks for the extra info. Looks like a to=0 was sneaking in the url

Fix dynamic graphs

[Roger]

Yep, that fixed it.

Thank you.
