hello i am wishing to plot 5 graphs showing the relationship between
x, the time of day in hours
y, the load upon a transformer
z, the penetration on the grid
I have all my y values as vectors like so;
FEV5=[0.55
0.4
0.4
0.4
0.4
0.4
0.4
0.6
0.8
0.82
0.83
0.81
0.8
0.85
0.75
0.77
0.78
1.215
1.5
1.425
1.35
1.335
1.275
0.55
];
i want to have a 3D graph that uses the z axis as a guide to that penetration level is being shown at that point, i basicly want 5 2d plots graphed one hebind the other in a 3d mannor with a spacing of 10% between them as the penetration goes from 0%-50%

The dimensions of the 5 different plots must be the same for the following to work. So make sure you pre-process your data accordingly.
N = 5 ; % No. of plots.
data_size = 200 ; % Length of data to be plotted.
t = 1:data_size ; % X-coordinates of the 2D grpahs.
data = rand(N,data_size) ; % Each row contains contains data for each 2D graph.
figure
hold on
for i = 1:N
plot3(t,i*ones(size(t)),data(i,:))
end

If you want to use custom values for 'z' :
N = 1:100:1000 ;
data_size = 200 ;
t = 1:data_size ;
data = rand(length(N),data_size) ;
figure
hold on
for i = 1:length(N)
plot3(t,N(i)*ones(size(t)),data(i,:))
end
