Replacing   xpolys(X,Y,zcol(1:$-1))
with  xsegs(X,Y,zcol(1:$-1))

is much better, noticeably if you wish to plot the projection onto
a z=/=0 plane. For instance, after the xsegs(...) instruction, doing

e = gce(); e.data(:,3)=3.5;

will raise the projection above the helix.

xpolys() will not allow that (or in a much more complicated way).
