The following figure is just a representation of a 2d array with surf. I would like to create a similar figure with 10 of these 2d arrays stacked on top of each other with some kind of offset along the z axis.
figure();
surf(X);
colormap(hsv);
shading interp;
campos([-70 -150 80]);
grid on;
set(gcf,'color','w');
Just call surf several times with hold on, applying a gradually increasing offset.
By default (1-input version of surf), the offset will affect the colors shown for each surface. Here's an example with three 2D arrays. Note that peak-to-peak amplitude is different for each one.
x{1} = .2*peaks(30);
x{2} = .4*peaks(30);
x{3} = .8*peaks(30); % cell array containing three 2D arrays
offset = 7; % desired offset
hold on
for k = 1:numel(x)
surf(x{k} + offset*(k-1))
end
campos([-100 -170 90])
grid on
To prevent offset from affecting color, i.e. achieve consistent color for all surfaces, use the 2- or 4-input version of surf to separately specify height and color:
x{1} = .2*peaks(30);
x{2} = .4*peaks(30);
x{3} = .8*peaks(30);
offset = 7;
hold on
for k = 1:numel(x)
surf(x{k} + offset*(k-1), x{k}) % Only this line has been changed
end
campos([-100 -170 90])
grid on
To generate stacked planes (no height variations) with color depending on value: modify the input arguments as follows:
x{1} = .2*peaks(30);
x{2} = .4*peaks(30);
x{3} = .8*peaks(30);
offset = 7;
hold on
for k = 1:numel(x)
surf(repmat(offset*(k-1), size(x{k})), x{k}) % Only this line has been changed
end
campos([-100 -170 90])
grid on
