Plot (x,y,z) triplets over coordinates (x,y) with color z

Question

I\'ve got a list of points (x,y,z) and would like to visualize them as a curve on a plane with points on (x,y) and any of color/intensity/thickness as z. How can this be don

Answer 1

The solution can be like that

x = 0:.05:2*pi;
y = cos(x);
planez = zeros(size(x));
z = x;  % This is the color, vary with x in this case, but you can use your vector
surface([x;x],[y;y],[planez;planez],[z;z],...
        'facecol','no',...
        'edgecol','interp',...
        'linew',2);

The point is that you are painting a surface, where the colors can easily modified. I dont think it can be done with plot
