How can I plot this type of figures?

I have three vectors x,y,z with 3000 elements each one.

I want to obtain the same type of plot shown in the figure (with all the specific color zones and colorbar on the right). I suppose that there are specific command, but I do not know them.

I have just tried to use surf, but the obtained graph is different...

Thanks in advance!

Using surf, did you take these steps?

L = membrane(3);
surf(L,"LineStyle","none") % don't display mesh
view(2) % view from top
shading interp % interpolated colors instead of faceted colors

If your x,y,z are in vector form rather than in X,Y grid format, you may need to first use a scatteredInterpolant and interpolate on a regular grid to use the surf() command.
