how can i plot this kind of graph?

Hi everyone, I need to plot this kind of graph in my paper. Can anyone give me some hints how to plot it by matlab? Thank you very much!

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.

I asked lots of my friends who are regarded as professional in matlab. None of my friends can plot. Thank you very much!!!

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

[Star Strider]

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
