Build a histogram for a quantity using data from log files. Each version allows histograms to be created for the set of quantities defined for that application. The histogram is written to standard output, in a form suitable for plotting. Here 'xxx' is a prefix identifying the particular incarnation of this program. For the format of the quantity specifications, see the documentation on generic quantities, quantities for Monte Carlo runs, quantities for neural networks, etc.
Data comes from records with indexes in the specified ranges within the log files mentioned.
The low bound defaults to one. If no high bound is given, the range extends to the highest index in the log file. The output consists as many lines as bins, with each line giving the value at the centre of the bin and either the count of values falling within the bin or the fraction of values falling within the bin. The latter option is selected by preceding the number of bins with a minus sign. Values falling outside the range are discarded, except that they affect the normalization of counts to give fractions.
