[9fans] plot(1) to file?

[sqweek]

 Hey guys,
 I've got some data I want to put in a graph. I got graph |plot going
easy enough, which gets me a nice pic on the screen, but I can't work
out how to generate an image file instead. plot(1) mentions troff
which convinces me that it is possible, I just can't figure out how.
 I'm using p9p, otherwise I could probably do something clever with
/dev/screen...

x allows similar tricks.  see xwd(1).

You could use grap(1) - the troff preprocessor.

 Ah right. That assumes I have an X server available though, which
isn't usually true on my server where I want a cron job to generate
the graphs. I guess I could mess about with Xvfb, but I should
probably take a look at grap(1) anyway... graph(1) has a nice easy
interface but I could do a better job of axes labels and the like with
finer control. OTOH, nothing to stop me inserting my own plot(1)
commands in graph's output...
 Well I should work something out. Thanks Steve, Erik.
