How plot a figure like this attached figure?

Hi,

I have some laser beam amplitude profile and I want to plot this profiles like follow fig in matlab.

infact, I have tried this codes

% z1 and z2 are defined in my script as 500*500 matrix
r1=linspace(0,0.005,500); 
r2=r1;
mesh(r1,r2,z1)
hold on
mesh(r1,r2,z2+2)

but I can not rotate and it not give what I want. I need help?

It's because mesh expects z-data to be actual coordinates in z, but mesh (and surf) will accept a 4th argument for color

N = 500;

r1=linspace(0,0.005,N); 
[X,Y] = meshgrid(r1);

figure; cla; hold on;
ax = gca;
% fig = figure;
% ax = axes(fig,'NextPlot','add');

for i = 1:10
	C = rand(N); % replace with the image
	Z = ones(N)*i;
	
	% flip the order of Y and Z to get vertical slices
	s = surf(ax,X,Z,Y,C,'EdgeColor','none');

end

ax.DataAspectRatio = [1,700,1] % stretch the "z"-axis view

% rotate the view
view([-65,14])

Dear Lee, thanks for your replying and attention.

I tried your code and got following error:

"Error using axes

Incorrect input args for

constructing axes object"

I could not to fix it. What must I do?

[J. Alex Lee]

that's odd...are you adapting my example to your code and that is failing? Or are you running my example as is and it is failing?

what is your matlab version? does the edited version of code above work?

[Habib]

I only run your example as is.

my matlab version is 2015rb.

[J. Alex Lee]

and what happens if you try the edited version above?

[Habib]

I will run your code in 2017rb version. After, I will insert the result as comment.

Dear Alex, Thank You so much.

Your code correctly work .
