You need two dimensions of sampling for something like this:

That hack was only possible by splotting to get an extra column out of
'+', and flattening to 2d with `set view map':

    splot '+' using 1:2:(0.0):(cos($1)):(cos($2)):(0.0) with vectors

Problem is that for 3d vectorfields, there's no 4d analog of splot to
flatten into a cube.
