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?

"plot3" creates a *single* line based on the x, y, z coordinates. What exactly do you want to accomplish with your example? What does it mean to change the color of a *single* line to 3 colors? Can you clarify your question?

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.
