No that is not the natural way. That is the way you pick afterwards if
you want your graph to resemble the metaphor. But it is not the way
people "naturally" graph these numbers, if the metafor was not put
into their head in first place. Certainly not people who actually study
these kind of things.

No the reason is, we prefer the graph to be a function. That is for every x
at most one y. Using the axes the other way around would mean that set backs
would result in multiple y values for the same x.
