Set the histogram values.
This method is used to correctly initialize the bins of the histogram. n is the number of valid intervals between minv and maxv. for a more robust working, the Histogram class stores also the two out of range intervals (-inf, minv] and [maxv, +inf) Each bin is left closed (eg it contains the value The gamma parameter is applied to modify the distribution of the ranges of the bins. Default uniform distibution.
