How to make point (0,0,f(2,3)) on z-axis as little dash instead of round point

Suppose I have function of two variables as in attached file. I want to draw little dash (red in example) on z-axis which represents value of function f(x,y). I don't want it to look like rounded point, because I want to emphasise that f(2,3) is number, not point (ordered triple) which seems to be only option.

But I would like that dash doesn't go bigger/smaller with zooming in/out. I just want it to looks like "ticks" on z-axis for example.

I beleive that could be managed, but don't know how :)
