On my scatter3 plot I wanted to draw a line from each point's marker on the plot, down to the surface plane, so the points can be visually differentiated by their height Z/length of line. Is there a way to do this?

Use the stem3 function.
If you want to colour the points, use something like this —
figure
stem3(X, Y, Z)
hold on
scatter3(X, Y, Z, 25, Z)
hold off
grid
That should work.
