How do I set properties for different vectors in a plot?

I want to set several properties of plot3. I have the handle, but I can't set different properties for the three vectors of the plot3.
For example:
handle=plot3(v1,v2,v3);
set(handle(1),'Color',[1 0 0]);
set(handle(2),'Color',[1 1 0]);
set(handle(3),'Color',[1 0 1]);
How can I resolve this?

Hi Jiro,
Yes of course.
I ask how I can resolve the issue of give one color per each vector of plot3 function.

PLOT3 creates a 3-Dimensional plot of your xyz data. It doesn't create three separate vectors. Perhaps you want PLOT, called 3 times (and HOLD ON)?

Is this what you're trying to achieve?

% 3 column vectors concatenated 
In = cumsum(rand(10,3));
plot(In)

plot3() will produce 3 handles if and only if one of v1, v2, or v3 is a N x 3 array with N at least 2. In such a situation, using set() the way you do should be fine.
In general, consider instead setting the axes ColorOrder property.
