Comments on Scalar that varies across one or multiple scalar axes

Scalar that varies across one or multiple scalar axes

+0
−1

I have recently read:

If anything has a quantifiable value that varies across one or multiple scalar axes, it's a signal, and you can study it.

What does "multiple scalar axes" mean?
I would assume it means something like a value on a map, traced by X,Y coordinates, but there might be an even more basic example.

It was a comment in StackExchange SignalProcessing for a now locked thread I don't want to link to.
