lol, I didn't even think that just resizing the window would widen the x-axis, thank you, that helped. And I checked out that log viewer, it's pretty handy too.
I'm talking about the windowed graph, the one you get when you right click on a value and click "show graph", and not the OSD graph.
Is there any way to extend the amount of time it shows? Say, 2 hours worth, instead of whatever it is now?
