How to make colorbar work for a scatter3 plot?

Hi,

I am plotting a set of scatter points using the below code. It works perfectly and the graph is correct. But the colorbar is just showing values between 0 and 1 and I don't know how I can reflect the actual values of the graph.

[NUM,LETTER]= xlsread('B.xlsx','S1');
M=NUM(:,1:3);

z=M(:,2)
y=M(:,1)
x=M(:,3)

[carbon,idx]=sort(z)

yyy=y(idx)

xxx=x(idx)

zzz=z(idx)

cmp=jet(numel(z))

scatter3(xxx, yyy, zzz, 15, cmp);

colorbar

I would appreciate any help. Thanks

Eg: To use scatter and color plot

x = linspace(0,3*pi,200);
y = cos(x) + rand(1,200);
c = linspace(1,10,length(x));
scatter(x,y,[],c)
colorbar

In your case try

scatter3(xx,yy,zz,[],zz) ; 
colorbar
