GRAPH(1)               DragonFly 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
       following 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
                   after 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
                   (endpoints 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.

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.
