Hi, I'm using the function [counts,centers] = hist(xxx,100) for histogram plot. Here centers gives the center value of each bin on X axis but I want its corresponding Y value. How can I find the Y value of each bin center of histogram ?

The Y value will be the counts value corresponding to the center you are interested in.

Sorry, I didn't get how it extracts the Y axis value of each bin center.

What Walter said. The Y value is the number of values or N in histcounts(). I you want the frequency, divide by the total number of values.

You might want to have a look at ksdensity() as well.
