I am working on a VI that records voltages from a DAQ and I need to be able to scroll left and right, back and forth through time using left and right keys. I am a beginner so please try to keep it simple, thank you!

Thank you so much for your reply! But what is the source for the stop? When I try to wire it to the event structure it acts like a sink.

It is wired in the stop event case from the inside.
The picture is actually a snippet. Simply drag it to the diagram and it will turn into fuctional code.

You can use an Event structure (responding to Key Down) and a While loop to update the graph's X scale.
I would probably use an array of two elements simplifying the increment/decrement operations and eliminating half the SRs. Instead it needs an index array before the property nodes, no big deal. 😉

I wish LabVIEW had this as the default frame in an Event structure instead of Timeout; I use this more often. This is cleaner than using a Stop button.
