grap(1)                                                   grap(1)



NAME
     grap - invokes a pic preprocessor for drawing graphs

SYNOPSIS
     grap [-Ttty-type] [-l] [-] [file]...

ARGUMENTS
     -    Specifies the standard input.

     file Specifies the file to be preprocessed by the grap
          command.

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

     -Ttty-type
          Specifies tty-type as grap's output device.  Currently
          supported devices are psc (POSTSCRIPT device such as
          the Apple LaserWriter) and aps (Autologic APS-5).  The
          default is -Tpsc.

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

        grap files | pic | troff | output-device

     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 transformations, and
     include data from files.  In addition, grap provides the
     same loops, conditionals, and macro processing that pic
     does.

FILES
     /usr/bin/grap
          Executable file
     /usr/lib/dwb/grap.defines
          File containing definitions of standard plotting
          characters
