PROGRAM:
NAME
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.
