x=[1 2 3 4 5 6 ];
y=[1 2 3 4 5 6 ];
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);

This can't be done with a single line object. It can be done with multiple line objects or with patch objects. This thread has examples of both.
