NAME
grap - pic preprocessor for drawing graphs
SYNOPSIS
grap [ files ]
DESCRIPTION
Grap is a pic(1) preprocessor for drawing graphs on a typesetter.
Graphs are surrounded by the troff `commands' .G1 and .G2. Data that
is enclosed is scaled and plotted, with tick marks supplied automati‐
cally. Commands exist to modify the frame, add labels, override the
default ticks, change the plotting style, define coordinate ranges and
transformations, and include data from files. In addition, grap pro‐
vides the same loops, conditionals and macro processing that pic does.
FILES
/usr/lib/grap.defines: definitions of standard plotting characters,
e.g., bullet.
