A quick look at http://www.gnu.org/software/gsl/manual/html_node/The-histogram-struct.html suggests no. The values in any given bin do not seem to be stored. You could, however, sort the original data and use a binary search to find the minimum and maximum value in any given bin using the bin boundaries from gsl_histogram's range member. Best of luck, Rhys
