How do get 'plumblines' for scatterplot points?

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.
