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 follow- ing 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. 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. GRAPH(1)
