graph - compile graphs into pic input
graph [ options ] [ filename ... ]
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
1 4 2 4 3 4 "straight across
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
-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
-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.
Workstation price performance from a Digital ad. Process with graph
-rev workstations | groff -TX75
"%T Workstation Price / Performance, 6/93 "%X SPECINT 92 Performance

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