NAME

grap − pic preprocessor for drawing graphs

SYNOPSIS grap [−Ttty_type ] [ − ] [ −− ]

OPTIONS

−T specifies tty_type as grap’s output device.  Currently supported devices are aps (Autologic APS-5) and di10 (Imagen Imprint 10).  −Taps is default. 

−l Stops grap from looking for a library file of macro defines, /usr/lib/dwb/grap.defines. 

DESCRIPTION

grap is a language for typesetting graphs.  It is also the name of the preprocessor that feeds input to pic(1).  Thus, a typical command line would appear as follows:

grap file(s) │ pic │ troff │ typesetter

Graphs are surrounded by the troff "commands" .G1 and .G2.  Data that is enclosed is scaled and plotted, with tick marks supplied automatically.  Command 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 provides the same loops, conditionals and macro processing that pic does. 

FILES

/usr/lib/dwb/grap.defines: definitions fo standard plotting characters, e.g. bullet.
