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(1:28,3),'or')
>> hold
But this returned a normal 2d plot as if i had used plot() instead of plot3()

I noticed that whereas
>> plot3(sc(29:3000,1),sc(29:3000,2),sc(29:3000,3),'.b')
creates a 3d plot,
>> h=figure; hold all
>> plot3(sc(29:3000,1),sc(29:3000,2),sc(29:3000,3),'.b')
>> hold
does not.

Can anybody tell me how i can have differently colored points in a 3d plot?
Thank You
Jody
