I am trying to creat a 3D surface plot with the contour of the surface projected on the top face (XY plane in Z = max)
Following is the code used:
f = figure('PaperSize',[8 8]);
Z = table2array(Table);
Z = Z(:,2:N+1);
Y = Table.Wavenumber_cm_1_;
X = [1:N];
SurfacePlot = surf(X,Y,Z);
ylabel('Wavenumber[cm^-1]');
xlabel('Aliquot Number');
zlabel('Absorbance[a.u.]');
colormap jet
shading interp
grid off;
hold on
contourf(X,Y,Z);
hold off
The problem is that the contour is created on XY plate (under the surface plot). How can move the contour up to the top surface?
Thank you.

contour() object have an undocumented property named ContourZLevel: https://stackoverflow.com/a/8055468/4346708. For example,
[X,Y] = meshgrid(1:0.1:10,1:0.1:20);
Z = sin(X) + cos(Y);
ax = axes();
hold on
view(3);
s1 = surf(X,Y,Z);
[~, s2] = contourf(X,Y,Z);
s2.ContourZLevel = 5;
