NAME

dataplot - Plot a data file: one or all columns

SYNOPSIS

Reads in a data-file containing one or more columns of int/float data. Plots them.

DESCRIPTION

dataplot:  plot one or all columns of a data-file. Show summary statistics.

USAGE:    dataplot.py  [OPTS]  infile.dat

OPTIONS:  -c, --column      N,sum,all   use Nth column's data (N is 0-based). [default: all].
           -t, --title       TITLE       override plot title
           -x, --xlabel      LABEL       override x-axis label
           -y, --xlabel      LABEL       override y-axis label
           -u, --ulabel      L,A,BE,LS   override legend labels.

           -o, --outplot     FILE.png    save plot as FILE.png/.jpg, "auto" names it after infile.

           -n, --noplot                  don't draw the plot window on screen (useful for testing/scripting).
           -h, --help                    show help.

INPUT:    Input file, infile.dat ('-' for stdin) should be columns of (int/float) data, separated by
           whitespace, with optional #comments, i.e. the standard form for numpy.loadfile(). cf. genffttest.
           (compressed files (.gz/.bz2) can also be read transparently, no need to uncompress first.)

NOTE:     dataplot.py can crash on larger datasets, especially on older PCs with less RAM.
           So, consider decimating the data in advance, or first copying the file to a more powerful machine.
