NAME
grap - pic preprocessor for drawing graphs
SYNOPSIS
grap [ files ]
DESCRIPTION
Grap is a pic(1) preprocessor for drawing graphs on a type-
setter. Graphs are surrounded by the troff `commands' .G1
and .G2. Data that is enclosed is scaled and plotted, with
tick marks supplied automatically. Commands exist to modify
the frame, add labels, override the default ticks, change
the plotting style, define coordinate ranges and transforma-
tions, 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.
