gbhisto2d1
Produce 2d histogram from data
Usage
gbhisto2d [options]
Overview
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. Transition matrices (option -M 5 and -M 8) have final states across the rows. In case of continuous variables it is also possible to consider rectangular matrices.
Options :
-
-M -
choose the statistics to print for each bin (default 0)
