Hi,

What I mean by the i axis, is imaginary numbers.  That is, I would
like to see the zeros at +2i and -2i as well as the parabola in x and
y.  If that makes sense?

ParametricPlot3D can be used to plot three dimensionsal curves. Plot3D can
be used to plot surfaces. Additionally, the package Graphics`Graphics3D` has
several other functions for 3D plotting.

You've not defined what you mean by the "i" axis and the expression you give
is only dependent on two variables.
