# maphimbu(1)

histogram builder for 1-d numerical and text data

## 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.
