I want to rotate the symbol(the marker) inside the figure, how to make the marker parrallel to X-Y surface as shown in fig.2?

thanks very much in advance

The closest MATLAB gets to this in the built-in facilities is that scatter3() creates markers as patch objects, which you could post-process to become discs.

You might be able to find something in the File Exchange; I do not recall having happened upon it, but I wasn't looking for it either.

thanks roberson! I would like to try it again and let you know the results later time.

Note: this solution will not work from R2014b onward.

Here is a simple basic part.

n = 100;
X = randi(n,30,1);  Y = randi(n,30,1);  Z = randi(n,30,1);
r = 4; % factor for radius scale
uZ = unique(Z);
cmap = jet(length(uZ));
for i = 1:length(Z)
    R = r * (mean(Z)/300 + (Z(i)-min(Z))/range(Z));
    [x,y] = pol2cart(0:pi/8:2*pi,R);
    z = zeros(length(x));
    C = cmap(uZ==Z(i),:);
    patch(x+X(i),y+Y(i),z+Z(i),C,'EdgeColor','none')
end
