You will supply your own answer.
As Robert says, there is no Z axis.

I will admit that I am probably mixing too many metaphors, and bearing in mind that calculus (along with calculating the height of an equalateral tetrahedron from base principles) made me retire early from an engineering degree, probably makes this comparison far from ideal. I could easily demolish my own argument and say that instead of being limited to putting black or not-black on the graph, I could just use various greys and even colours and then keep everything in 2 dimensions. My ponderings were along the lines of whether there was anything truly revolutionary about digital imaging, due to the ability of recording tone at a point by point level, which gives us a new thingy to use in photography, which may have a significant impact on our perception of produced images. At the moment I think not.
Additionally, due to my own lack of inertia, I have not found out what the comparitive size of a silver grain is relative to a digital imaging sensor and the ratio of not-sensor to not-grain is, which probably has more influence over the whole affair.
I will also admit that there aren't 3 dimensions. We are lumpy things in space and science is purely a human construct.
