HIST3: Stata module to draws histograms for intervals of different size
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.
