       maphimbu -  1-d histogram builder for numerical and text data


       maphimbu [OPTION]... [FILE]


       This program produces 1-d histograms from numerical or text data input.
       It can be also used to estimate the probability  distribution  function
       of          a          numerical         variable         -         see


       -x <int>
              x-data column (default is 1)

       -X     treat hole line as one string (single data record)

       -y <int>
              y-data column  (default  is  2);  It  is  considered  only  when
              combined with ’-m’ or ’-S’

       -d <float|int>
              delta  size  (dx-resolution)  in case of numerical data; Keep in
              mind that 2 is not the same  as  2.0:  in  the  first  case  the
              numbers are treated as integers, in the latter as floats.

       -n     normalize   the   result   A)   non-numerical   data:   n(x)   =
              counts(x)/sum_of_counts  B)  numerical  data:   the   normalized
              probability density func.

              is  P(-INF  <  x  <INF)  =  Int_[-INF:INF] P(x)*dx = 1 ; For the
              numerical integration an open x-data interval is assumed.

       -N     normalize data against the total sum of counts (same  as  option
              ’-n’ with case A forced)

       -U     normalize  the  result with x-range mapped to unit; The x-values
              are mapped to the interval [0:1], respectively Int_[0:1] P(x)*dx
              = 1; This option is mutually exclusive with ’-n’.

       -S     compute  sums  and normalized sums of y-values; The total sum of
              all y-values is used for the normalization.

       -m     compute the arithmetic mean of y-values in the respective x-bar

       -C     center histogram bars (shifts x-axis by 0.5*dx)

       -s <int>
              sort output numerically using the specified column;  It  is  not
              working correctly if header output.

       -r     do reverse sorting (in combination with ’-s’)

       -H     print a data description header

       -V     print program version and exit

              output version and copyright information

       --help display help

       -h     display short help (options summary)

       Note:  this  program  is  not  intended for use in high order numerical
