Hi, I am wondering if I have two values
x=[1,2,3,4,5,6,7]
y=[10,20,22,25,30,35,37]
I understand, it does NOT work like that, but could anyone help me to to do the same figure but with the data on the righthand side Y..
I need my plot to look like the same ??

Another question, I read about slice, but I do not usually understand what is V ??

You need at least 4 variables (3 independent and 1 dependent) to use slice(). V corresponds to the color of slices.

Try this
[X, Y, Z] = meshgrid(0:0.5:20, 0:0.5:20, 1:7);
V = exp(-0.2*sqrt((X-10).^2+(Y-10).^2+(2*(Z-4)).^2)); % based on guess
slice(X, Y, Z, V, [], [], 1:7)
colormap(jet)
shading interp
view([45 10])

Hi,
Thanks for your help, it's great man, but could I add an axis on the right side with number for each stack layer ??
May also to define a shape for each stack layer or color then add color bar with label ?
Also, could I add labels ?? for each axis ?
Looking to hearing your reply.

"could I add an axis on the right side with number for each stack layer ??"
Not easy to do programmatically, I suggest you add those labels using textboxes manually. In the figure window, go to the "insert" menu and click "Textbox". You can then you can manually click the position where you want to add the textbox.
The following code adds colorbar and the labels on each axes.
[X, Y, Z] = meshgrid(0:0.5:20, 0:0.5:20, 1:7);
V = exp(-0.2*sqrt((X-10).^2+(Y-10).^2+(2*(Z-4)).^2)); % based on guess
slice(X, Y, Z, V, [], [], 1:7)
colormap(jet)
shading interp
view([45 10])
colorbar;
xlabel('x');
ylabel('y');
zlabel('z');

Thank you so much,
I also asked to add label or specific color for each stack layer ?
Is it possible or even a direction for each stack layer ? hope so
thank you so much.. Your answer always appericated. :)

Can you elaborate on what do you mean by the labels or colors for each stack layer? Are you talking about numbers 12, 20, 22, 23, ... in red boxes in the original image? If yes, then the easiest way is to add them manually using textboxes, as mentioned in my last comment?

Like I have 7 stack layers, so I would like 7 different colors or lets say 2 of them with same colors and the rest (5 stack layers with another color) as the following:
Stack layer 1 (red)
Stack layer 2 (blue)
Stack layer 3 (red)
Stack layer 4 (red)
Stack layer 5 (black)
Stack layer 6 (blue)
Stack layer 7 (green)
it's like in plot function when you define the line color as the following:
plot(x,y,'r') it means red for these points and so on....

Although possible, there is no straightforward way. It cannot be done the same as passing color to plot(). The following threads will be helpful, but it will require some digging around.
