The data are inside the histogram but you've got to go "handle diving" to retrieve them if you didn't save the object handle when called it; if you did then see the 'Properties' section of the doc for it (link to in the 'See Also') section. All in all, it's easier to just use histcounts.

Histogram computation

WebbA histogram is an approximate representation of the distribution of numerical data. The term was first introduced by Karl Pearson . [1] To construct a histogram, the first step is to " bin " (or " bucket ") the range of values—that is, divide the entire range of values into a series of intervals—and then count how many values fall into each interval.
