This will get you started:

N = 10;
[X,Y,Z] = sphere(N-1);
Xr = randi(20, 10, 1);
Yr = randi(20, 10, 1);
Zr = randi(20, 10, 1);
for k1 = 1:N
    Xv{k1} = X + Xr(k1);
    Yv{k1} = Y + Yr(k1);
    Zv{k1} = Z + Zr(k1);
end
figure(1)
surf(Xv{1}, Yv{1}, Zv{1})
hold on
for k1 = 2:N
    surf(Xv{k1}, Yv{k1}, Zv{k1})
end
hold off
set(gca, 'Box','on', 'BoxStyle','full', 'XTick',[], 'YTick',[], 'ZTick',[])
grid off
axis equal

This will produce a plot similar to ‘B’. You will have to experiment with the patch function to get the box colors in ‘A’.

See the documentation for the relevant functions for details on how to use them.

Do you know how can I make the sphere color change with data? Thank you!

I thought they did in the plot in my code. There weren’t many spheres, so the color change wasn’t as obvious as it would be with more.

It’s a bit more obvious in this slightly revised code:

Nf = 10;                                                    % Sphere Faces
[X,Y,Z] = sphere(Nf-1);
Ns = 250;                                                   % Number Of Spheres
Xr = randi(20, Ns, 1);
Yr = randi(20, Ns, 1);
Zr = randi(20, Ns, 1);
for k1 = 1:Ns
    Xv{k1} = X + Xr(k1);
    Yv{k1} = Y + Yr(k1);
    Zv{k1} = Z + Zr(k1);
end
figure(1)
surf(Xv{1}, Yv{1}, Zv{1})
colormap(jet)
hold on
for k1 = 2:Ns
    surf(Xv{k1}, Yv{k1}, Zv{k1})
end
hold off
set(gca, 'Box','on', 'BoxStyle','full', 'XTick',[], 'YTick',[], 'ZTick',[], 'LineWidth',2)
grid off
axis equal
