maphimbu - histogram builder for 1-d 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 http://en.wikipedia.org/wiki/Probability_density_function.
-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.
