[9fans] Getting output from plot(1)

[9fans] Getting output from plot(1)

[John Floren]

I'm writing a little script to make venti usage graphs, and now that
I'm near the end I'm trying to use plot(1) to plot my data. However, I
can't seem to figure out any way of actually getting plot's output
into something like a png file. Suggestions?
Thanks

the only output driver for plot on plan9 is /dev/draw, you can
display it and then grab the image from /dev/wsys - not so easy
from cron though.

You could use grap(1) but you can only get to ps and pdf
from there (I think).

why not save the plot(6) format output and format it later?

the easy solution is to have  plot(1) create an image.

it would be even more interesting if rio could use a fake
framebuffer.

it's a short step from 1 fake frame buffer to n fake 
framebuffers and 1 real one.  this has got to be more
interesting that porting the sdmv50xx driver to the cpu
kernel. ;-)

hola,

I think gabriel diaz wrote something like what you are looking for,
it's somewhere in www.9grid.es (I can't tell where, because it's not
reachable from here.)
