normalize a histogram in matlab 2013b

hello all ,

i have a similar issue as in https://www.mathworks.com/matlabcentral/answers/266306-how-to-normalize-a-histogram#answer_208254

i need the same that is my y axis should be in probability and my x-axis should remain same (not the number of bins).

since their is no direct normalization function in 2013b version i am using

h = hist(z);
h =h/sum(h);
bar(h);

using bar(h) i get my y axis in probabilities,but my x-axis limits to number of bins. i need the x-asix range same as the one i get when i do hist(z).

in advance ,thanks for the help

[h, x_centers] = hist(z);
h = h/sum(h);
bar(x_centers, h);
