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.

在 MATLAB Online 中打开

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])

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.
