Dear everyone,
I want to draw a figure with 3-d data (x,y,values),and I want to rank the values then the different ranks value are with different color as you can see from figure2.
Anyone know the answer?Thanks in advance.

Now I have find a easy and beautiful method to do this
scatter3(locationX,locationY,RSSValue, 'CData',RSSValue);
just with 'CData',RSSValue parameters, we can do this

x = rand(100,1) ;
y = rand(100,1) ;
z = rand(100,1) ;
%%get indices according to values
idx = 1:100 ;
idx1 = z >0. & z<=0.4 ;
idx2 = z >0.5 & z<=0.8 ;
idx3 = z >0.8 & z<=1 ;
%%plot
figure
hold on
scatter3(x(idx1),y(idx1),z(idx1),'r','filled')
scatter3(x(idx2),y(idx2),z(idx2),'b','filled')
scatter3(x(idx3),y(idx3),z(idx3),'g','filled')

thanks for your answer. I think the result is right. And it looks nice nut not enough. can I ask one more question about this? the question is as you can see this link https://cn.mathworks.com/matlabcentral/answers/334739-rank-the-point-in-scatter3d-figure-with-different-color#answer_262568

And I can edit the figure with the "MATLAB figure editer"
function createfigure(locationX1, locationY1, RSSValue1, S1, RSSValue2)
%CREATEFIGURE(LOCATIONX1, LOCATIONY1, RSSVALUE1, S1, RSSVALUE2)
% LOCATIONX1: scatter3 x
% LOCATIONY1: scatter3 y
% RSSVALUE1: scatter3 z
% S1: scatter3 s
% RSSVALUE2: scatter3 c
I think we should use something like the S1 as the parameter of the scatter3 function
