different point colors in plot3?
Hi I try to do a 3 dimensional point plot where different groups of points have different colors. In analogy to the 2-dimensional plot i used hold to do several plot3 commands in the same figure: h=figure; hold all plot3(sc(29:3000,1),sc(29:3000,2),sc(29:3000,3),'.b') plot3(sc(1:28,1),sc(1:28,2),sc(1:28,... 1 Jul 2010 09:57
