My apologies. I had forgotten that that plot used explicit arrows
rather than the zero-axis lines.

The plot which was annoying me was actually a different one,
the one I recently constructed for rgb_variable.dem;
when Daniel mentioned the plot in pointsize.dem, I falsely
concluded that it was a parallel case.

I will construct a full example pair if you like, but my observation
is that in case such as the final plot in rgb_variable.dem, the axes
are properly occluded by other plot elements if you draw them by
including a dataset of  unit vectors in 3D, but not properly occluded
if you draw them via the "set zeroaxis" command.
Quite probably a bug in the code I added myself.
