2d surface plot matlab

I have x1,y1,z1.... xn,yn,zn.. and at each point I have the resultant value measured by experiment. Now for each plane I want to plot a surface plot. image of scatter3 with gridpoints is attached. scatter3 gives me 3d grid.

if 
  scatter3(x, y,z,20,resultantvalue);
end

did you try "surf" and "mesh". They do exactly that:

surf - Surface plot :This MATLAB function creates a three-dimensional surface plot.

mesh - Mesh plot: This MATLAB function draws a wireframe mesh with color determined by Z, so color is proportional to surface height.

If you want to have all in a 2-D plot, pcolor does the trick

Thankyou Jesus, for your reply. Hope you see the attached figure and hopefully I was good to explain. As the figure shows I have 5 planes and each plane has x, and y points, for which I have corresponding values of intensity. I am not able to interpolate all points by using mesh. I use [X Y] = meshgrid[x y], which converts them into matrix, but then I am not able to interpolate values of intensity for these x and y.

Hmm so you want to represent 5 different "surfaces" in only one figure. Is that right? If that is right, maybe something like:

 figure
hold on
for i=1:5
     mesh(X,Y,z(i,:))
end
hold off

If this is not what you intended I am sorry I think I do not understand you :(

Thanks, Sanchez, It will probably help.

Maybe the function griddata() does the job?
