Random layered non-overlapping scatter plot in MATLAB

I am plotting (for example three) different datasets using scatter or plot with the hold on function consecutively. This generates a scatter plot with the last layer overlapping with all the other ones. Is there a (plotting) function that can randomly disperse the layers?

One way you could achieve this is via a 3d plot.

Create a depth vector of the same length as your x & y vector with random numbers and plot using plot3 (instead of plot).

You can then use the command view(2) to change the viewpoint you will get the effect you are after.

Example

f1=figure;
f2=figure;
nValues = 2000;
for dataSet=1:3
    r1 = rand(nValues,1);    
    r2 = rand(nValues,1);    
    r3 = rand(nValues,1);
    t = r1 * pi * 2;
    x = r2 .* cos(t) + r1(1);
    y = r2 .* sin(t) + r2(1);
    depth = r3;
    set(0,'CurrentFigure',f1)
    plot(x,y,'.', 'MarkerSize',25)    
    hold all

    set(0,'CurrentFigure',f2)
    plot3(x,y,depth,'.', 'MarkerSize',25)    
    hold all
end
% Change viewpoint 
view(2)
