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

SYNOPSIS

maphimbu [OPTION]... [FILE]

DESCRIPTION

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
http://en.wikipedia.org/wiki/Probability_density_function.

OPTIONS

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

-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 average of the y-values in the underlying x-bin

-a     compute accumulated sums of the result data column (default is colum  2,  or  3  in
case of normalization); The program 'mintegrate' is need in this case.

-s <int>
sort output using the specified column; Header is skipped in this case.

-g <int>
sort output numerically using the specified column; Header is skipped in this case.

-r     do reverse sorting (in combination with '-g' and '-s')

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

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

-H     print a data description header

-V     print program version and exit

--version
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 computations.
