hist3 draws histograms for intervals of different size. To do this, varname is grouped into intervals according to the cutpoints in the value-option. Then for each interval a bar is drawn with width equal to the width of the interval and height equal to f_j/(h_j*n), where f_j = the absolute frequency of the interval j, h_j = the width of j and n = number of nonmissing observations. The heigths of the bars therefore reflect the density of the interval, and the area reflect the frequency of the interval.
