color vector in plot

Is it possible to write

plot(x,y,color)

where x, y and color are all arrays of the same length. color is an array to set a color for all points drawn by x and y arrays, i.e. coordinate (x(i), y(i)) has a color: color(i). It's easy to write in the component form in a for loop, but I'd like to write in the vector form.

Read about scatter . Also check the below option:

x = 0:.05:2*pi;
y = sin(x);
z = zeros(size(x));
col = x;  % This is the color, vary with x in this case.
surface([x;x],[y;y],[z;z],[col;col],...
        'facecol','no',...
        'edgecol','interp',...
        'linew',2);

Thank you. What does [x;x] etc mean? Why not just surface(x,y,col), as in scatter(x,y,10,col)?

I need col to be a color string.
