GRAPH(1)		    General Commands Manual		      GRAPH(1)

NAME
       graph - compile graphs into pic input

SYNOPSIS
       graph [ options ] [ filename ...	 ]

DESCRIPTION
       graph  is  a  perl  script which	takes sets of X	Y data and generates a
       (human readable)	pic program that will produce the graphed  data.   The
       output  is designed such	that you can save it in	a file and tweak it to
       make it fit your	document.  Try one and look at the output.  The	output
       is actually commented.

       The graph is autosized and auto ticked.

       The  input  data	format is similar that of xgraph(1), i.e., 1 1 2 2 3 3
       "sloped across

       1 4 2 4 3 4 "straight across

CONTROL	OPTIONS
       You may set the graph title, the	X title, and the Y title with the fol-
       lowing control sequences	in the data stream: %T Graph title in +4 point
       font %X X axis title and/or units in +2 point  font  %Y	Y  axis	 title
       and/or  units in	+2 point font %fakemax-X <value>     force graph to be
       that big	%fakemax-Y <value>     force graph to be that  big  %fakemin-X
       <value>	    force  graph to be that small %fakemin-Y <value>	 force
       graph to	be that	small

OPTIONS
       -rev	   reverse X/Y data sense (and titles).	 Note this is done af-
		   ter processing any fudging of the input data	stream(s) (see
		   -xk,	-yk, -logx, etc	below).

       -below	   put data set	titles below the  graph	 rather	 than  to  the
		   right.

       -close	   no extra space around the data's endpoints.

       -qline	   connect the quartile	center points.

       -grid	   dotted line grid marks.

       -nobox	   no box around whole graph.

       -big	   make	the graph take the whole page.

       -medium	   make	the graph take about 1/2 the page.

       -small	   make	the graph be small.

       -grapheach  draw	each data set in its own graph.

       -nolabels   no X/Y/Title	labels.

       -nodatal	   no data set labels.

       -nomarks	   do  not  mark  each	data point with	distinct markers (end-
		   points are still marked).

       -k	   print values	larger than 1000 as value/1000.

       -xk	   multiply X input by 1024 (blech).

       -yk	   multiply Y input by 1024 (blech).

       -xm	   multiply X input by 1024*1024 (blech).

       -ym	   multiply Y input by 1024*1024 (blech).

       -logx	   convert X input into	lag base 2 of X	input.

       -logy	   convert Y input into	lag base 2 of Y	input.

EXAMPLE
       Workstation price performance from a Digital ad.	  Process  with	 graph
       -rev workstations | groff -TX75

       "%T  Workstation	 Price	/ Performance, 6/93 "%X	SPECINT	92 Performance
       "%Y Price in $1000's 35 5 65 10 78 15 110 70 "Dec AXP line

       25 4 25 8 38 16 48 21 52	23 64 27 "Sun SPARC line

QUARTILE FORMAT
       Data points are x y1 y2 y3 y4 y5.   You get a two lines from the	 first
       two y values, a mark at the third, and another line from	the last two.

SEE ALSO
       gtroff(1), gpic(1), perl(1).

BUGS
       This should probably be called pic_graph	or something like that.

       This  isn't done	as much	as I would like.  It isn't integrated with the
       groff preprocessor yet.	It doesn't know	about .GS/.GE things.	I  use
       it to manually generate a pic file and then include that.
