How to plot 3D scatter plot with legends?

I want to plot 3D scatter plot, change in colour with the label attached to the data point. Is it possible in Matlab or simply should I just move to "ggplot" package and learn R language which is best in graphics and it is free as well? Just let me know. Thank You.

N = 10 ;
x1 = rand(N,1) ; y1 = rand(N,1); z1 = rand(N,1) ;
x2 = rand(N,1) ; y2 = rand(N,1); z2 = rand(N,1) ;
x3 = rand(N,1) ; y3 = rand(N,1); z3 = rand(N,1) ;

figure
hold on
scatter3(x1,y1,z1,'MarkerEdgeColor','r','MarkerFaceColor',rand(1,3))
scatter3(x2,y2,z2,'MarkerEdgeColor','b','MarkerFaceColor',rand(1,3))
scatter3(x3,y3,z3,'MarkerEdgeColor','g','MarkerFaceColor',rand(1,3))

legend([{'First'},{'Second'},{'Third'}])

@KSSV

Why do you need the curly brackets in the legend ?

i believe it works like this:

legend('First','Second','Third');
