There is one simple answer: copy your matrix column to a Stata
variable and use -histogram-. Anything else will just be roundabout or
approximate.

Working in Stata12, I need to plot the histogram of the data contained in
the column of the matrix MAT.

I understand that, probably, a first step requires to use mm_histogram(), as
I did in the following example, but then I do not know how to proceed
(either in Stata or in Mata).

*---------------- start example ------------------

mata:

         mata mlib index

         MAT = uniform(100, 1)
         hist_data = mm_histogram(MAT)

end

*----------------- end example -------------------
