PLOT4 Plot colored lines and points in 3-D space
PLOT3(x,y,z,c), where x, y, z and c are four vectors of the same length N, plots a line in 3-space through the points whose coordinates are the elements of x, y and z, colored according to the values in c. The line consists of N-1 line segments.
Various line types, plot symbols and colors may be obtained with PLOT3(X,Y,Z,s) where s is a 1, 2 or 3 character string made from the characters listed under the PLOT command.
Example: A helix:
t = 0:pi/50:4*pi;
PLOT4 returns a column vector of handles to lineseries objects, one handle per line segment.

Hey! Got a problem.
I have created a [X,Y,Z]=meshgrid(x,y,z) for my computed data corresponding to the x,y,z. lets say we have c(x,y,z)=data in a loop.
No i wanna distinguish the data field into a stable data and unstable data. So I want to plot in one plot the data points with a value of less or equal 1. I thought about setting it NaN case 1 and the other way round. But got an error msg.
Help is very welcome.
very easy to use and understand. Thanks.
code is easy to be understand.
some useful commands
