Queries are working but graphs on forms have stopped

[MFS]

Ran into something very weird today.


Upon arriving to the office I noticed that the graphs that are on my user forms were not showing data. These graphs are being generated from queries and have been working for months now. I have not changed anything so this is troublesome.
Hopefully someone can help.

Okay, I rebooted my server and the graphs are now working again.
I do remember some time ago I had this exact issue.
I'm going to mark this thread as closed but if someone does know what could be causing this issue please post.
Thank You
