Plotting 2D graphs in scatter3

I want to plot the 2D projections of the scatter3, is it possible? Heres what I have until now:

figure

[x,y,z] = sphere(16);

x = [19.39,12.65,21.1,15.19]; %B

y = [4.58,1.76,6.38,5.43]; %A

z = [82.42,74.16,81.41,79.25]; %L

scatter3(x,y,z,...

          'MarkerEdgeColor','k',...
          'MarkerFaceColor',[0 .9 .75])
      C = [0 .9 .75; 1 0 0; 0 0.4 0.4; 0.6 0.4 0];
  scatter3(x,y,z,[],C,'filled','MarkerEdgeColor','k');
      text (18.39, 4.58, 81.42, 'Resina 3')
      text (13.65, 1.9, 75.16, 'A2')
      text (22.1, 6.38, 82.41, 'Resina 2')
      text (15.19, 5.9, 78.9, 'Resina 4')
  axis ([5 30 0 10 70 90])
  xlabel('*B')
  ylabel('*A')
  zlabel('*L')
  view(35,10)

Onto what would you project the scatter points?

A plane made up of 2 cartesian axis? A 2D plane which minimizes the distance to the scatter points? (e.g. for dimensionality reduction) Something else? What is the significance of the sphere() on line which does not seem to be used?
