NAME

   gbplot - gnuplot command line interface

SYNOPSIS

   gbplot [options] [command] [specstring] < datafile

DESCRIPTION

   This  command  produce  simple  plots  from  the command line using the
   'gnuplot' program. 'comand' is one of the gnuplot commands:  'plot'  or
   'splot'  while  'specstring'  is  a  list of gnuplot specifications. In
   order to escape shell interpretation place 'specstring' between  double
   quotes.  It is possible to specify the type of terminal and output file
   name as  command  line  options.  It  is  also  possible  to  start  an
   interactive  session,  useful  to  adjust  plot parameters by hand. The
   program can be used in a shell pipe, as in

   cat datafile | gbplot [options] [command] [specstring]

OPTIONS

   -h print this help

   -i start interactive session after the plot

   -T set a different terminal

   -o set an ouptut file

   -t assign a title to the plot

   -p prepend expression to plot command

   -l set log; possible values x,y and xy

   -C command to be run before the plot

   -v verbose output: print commands to standard error

   --help
          same as '-h'

   --version print the program version

EXAMPLES

   Two plots: one using line and one using points.

          echo "1\n2\n3" | gbplot plot "u 0:1 w l title 'line', '' u 0:1 w
          p title 'point'"

   Save the plot in PDF format in a file named 'test.pdf'

          echo "1\n2\n3" | gbplot -T pdf -o test.pdf plot "u 0:1 w l title
          'line'"

   Set log on the y axis

          echo "1\n2\n3" | gbplot -l y plot "u 0:1 w l title 'line', ''  u
          0:1 w p title 'point'"

   Set log on the x axis and a grid

          echo "1\n2\n3" | gbplot -l x -C "set grid" plot "u 0:1 w l title
          'line', '' u 0:1 w p title 'point'"

   Set a grid and the position of the legend

          echo "1\n2\n3" | gbplot -C "set grid" -C "set key bottom  right"
          plot "u 0:1 w l title 'line', '' u 0:1 w p title 'point'"

   Compute  the  value  of  the gamma function on a set of points; gawk is
   used to filer the relevant numbers

          echo "1\n2\n3" | gbplot -C "set table" plot 'u  (gamma(--help))'
          | gawk '/ i/{print }'
