How to Manage the Order of Graphics Objects and Plots on an Axes Object?

How to manage to specify the order of p1,r1, and r2?

For example, how can I put p1 between r1 and r2?

f = figure;

p1 = plot(-2:4, rand(1, 7))
r1 = rectangle('Position', [0 0 2 2], 'FaceColor', 'r');
r2 = rectangle('Position', [1 1 2 2], 'FaceColor', 'g');

axis([-2 4 -2 4])

Simply by creating the objects in the wanted order:

f = figure;
axes('NextPlot', 'add');  % As: hold on
r1 = rectangle('Position', [0 0 2 2], 'FaceColor', 'r');
p1 = plot(-2:4, rand(1, 7))
r2 = rectangle('Position', [1 1 2 2], 'FaceColor', 'g');
axis([-2 4 -2 4])

Or afterwards using uistack:

uistack(r2, 'bottom');
uistack(p1, 'top');
uistack(r1, 'top');

Alternatively (perhaps required with the OpenGL renderer), you can define a Z-value for the objects and set the 3D view accordingly. Then plot3 is needed, or the line command, and patch objects.
