.SH NAME
gbhisto2d \- Produce 2D histogram from data
.SH SYNOPSIS
.B gbhisto2d
[\fI\,options\/\fR]
.SH DESCRIPTION
2D histogram on a regular grid. Data are read from standard input as couples
(X,Y). If data are treated as continuous, equispaced bins are built and their
center coordinates together with the required statistics are printed. For
discrete variables, bins are built directly from the given variables.
.SS "Options :"
.TP
\fB\-M\fR
choose the statistics to print for each bin (default 0)
.TP
0
occurrences number for continuous binned variables (*)
.TP
1
relative frequency for continuous binned variables (*)
.TP
2
empirical density  for continuous binned variables (*)
.TP
3
occurrences number for discrete symmetric variables (bins{X}=bins{Y})
.TP
4
relative frequency for discrete symmetric variables (bins{X}=bins{Y})
.TP
5
transition matrix  (X=>Y)
.TP
6
occurrences number for discrete asymmetric variables
.TP
7
relative frequency for discrete asymmetric variables
.TP
\fB\-n\fR
number of equispaced bins where the histogram is computed. For output marked
with (*),  use comma ',' to specify different values for x and y coordinates.
(default 10)

verbose mode
.TP
\fB\-F\fR
specify the input fields separators (default " \et")
