How can I plot an X(as time) and a Y, and then another Y(with fewer points) as a colormap on the XY plot

How can I plot Time on the x axis, and a y, with a second y ( fewer elements) as a colormap on the line created between the XY plot.

 %%your fewer points 
  data = rand(10,3) ;
  x = data(:,1) ; y = data(:,2) ; z = data(:,3) ;

x0 = min(x) ; x1 = max(x) ;
y0 = min(y) ; y1 = max(y) ;

N = 50 ;

xi = linspace(x0,x1,N) ;
yi = linspace(y0,y1,N) ;
[Xi,Yi] = meshgrid(xi,yi) ;

Zi = griddata(x,y,z,Xi,Yi) ;
surf(Xi,Yi,Zi) ;
colorbar
