xlabel('Fspl,Rician,Rayleigh')
ylabel('Success')

You could try a similar approach to the one given below (just extend it for your purposes):

p1X = [1 2 3]; p1Y = [1 4 5];
p2X = [4 5 8]; p2Y = [1 5 2];

p1 = bar(p1X,p1Y);
hold on;
p2 = bar(p2X,p2Y);
set(p1,'FaceColor','red');
set(p2,'FaceColor','blue');

So you have different series now.

PS. After you paste code in your question, select it and press the "{} Code" button.
