How about calling hist() and bar() or plot()?
data = randn(1, 120)
[counts, binCenters] = hist(data, 16)
counts = counts / sum(counts); % Normalize
bar(binCenters, counts)
grid on;

You're welcome. You can vote for answers if you want to "thank" the poster with reputation points. Now, with recent releases of MATLAB, we use histcounts() or histogram() instead of hist().
