I am not certain what you are asking.

The plot appears to be by the stem3 function.

Try this:

x = randn(1, 10);
y = randn(1, 10);
z = randn(1, 10);

figure
stem3(x, y, z, 'filled')
hold on
xl = xlim;
yl = ylim;
hs = surf(xl, yl, zeros(size(xl(:)*yl)));
set(hs, 'FaceAlpha',0.2, 'FaceColor',[0.6 0.6 0.6])
hold off
grid on

producing:

Experiment to get different results.
