v.to.gnuplot

NAME

v.to.gnuplot - outputs an ASCII vector map in GNUPLOT format
(GRASS Shell Script)

SYNOPSIS

v.to.gnuplot help
v.to.gnuplot name

DESCRIPTION

v.to.gnuplot is an awk shell script that converts an ASCII vector map into a format suitable for plotting with g.gnuplot and writes the results to standard output.

OPTIONS

This program runs non-interactively; the user must either state all parameter values on the command line or use redirection.

Parameter:

name: Full path of an ASCII vector map layer.

EXAMPLE

Typing the following at the command line:

v.to.gnuplot < LOCATION/dig_ascii/elevation > elev.dat

will write the raster data to elev.dat. After staring the GRASS graphics monitor, the following dialogue:

g.gnuplot
gnuplot> plot 'elev.dat' notitle with lines

will plot a map of elevation.

NOTES

Output may be saved as PostScript, FrameMaker, TeX, etc (approximately 2 dozen output formats).

v.clean and v.out.ascii, must be run prior to v.to.gnuplot.
