Sorry,  I assumed you had saved the graphs.

If have the data you can use  -twoway__histogram_gen-  to obtain the
information:

. clear

. sysuse sp500
(S&P 500)

. twoway__histogram_gen volume, display
(bin=15, start=4103, width=1280.3533)

. return list

scalars:
                  r(N) =  248
                r(bin) =  15
              r(width) =  1280.353333333333
              r(start) =  4103
                r(min) =  4103
                r(max) =  23308.3
               r(area) =  1

macros:
               r(type) : "density"
