Do you have code to create the plot?

Here are 3 methods of animation you could apply to your data.

I considered a random function to plot the animation of a multivariable function.

x = linspace(-2,2);
y = linspace(-2,2);
z = linspace(-2,2);
[X,Y,Z] = ndgrid(x,y,z) ;
for i = 1:100
    fxyzOut(:,:,i) = randFun(X(:,:,i),Y(:,:,i),Z(:,:,i));
    surf(X(:,:,i),Y(:,:,i),fxyzOut(:,:,i)/1000) ;
    drawnow
    pause(0.05)
end
function fxyz = randFun(x,y,z)
fxyz =((1-x).^2)+(100*((y-(x.^2)).^2)) + ((1-z).^2)+(100*((y-(z.^2)).^2));
end
