rectangle() the backgrounds into existence and hold('on') and then plot;

or/

patch() the backgrounds into existence (either before or after the
plotting), but make sure that you use a z coordinate less than 0 for the
patches [or else no matter which order you draw them in, they might end
up on top, if you are using OpenGL as the renderer.]
