It looks like fit3d was the wrong verb; the other plot3d types use
fitgrafxy3d. I think the problem with fit3d is that fitxyz does some of
the same transformation as Tfm does. This is changed to use fitgrafxy3d
and cleaned up a bit.
plot3d_dot_jzplot_ =: 3 : 0
'x y z'=. y { Data
dat=. 1 |: (x ,: y),"2 1 citemize z
shape=.$dat
dat=.}:"1 project ,/ dat
dat=.(-1{shape) ]\ fitgrafxy3d dat
clr=. getitemcolor #dat
for_d. dat do.
drawdot iDATA;(d_index{clr);PENSIZE;d
end.
