You are not treating time as a dimensional axis. If there is only the 'now' then there can be no other points on the time axis, hence, no axis at all.

But there are other points on the axis, there's just nothing at these points.
Then all graphs that have time as an axis would have no points except at the present.
If the only active point on a time axis (ever) is the present, that can be used to locate an object, then it is not an axis.
Dimensional axes enable us to locate things in space (or space-time). If you are saying that going back to a point, in space-time, where something existed, and it isn't there, then you haven't traveled in time to that point in space. That would be what time travel is.
