Interface with `gnuplot` via a pipe

Open nuxeh opened this issue 7 years ago • 2 comments

Hello, you can send data to gnuplot without using a temporary file, on unix-like OSes at least, by using popen to spawn gnuplot and write data and commands to it via a pipe, similar to what's mentioned at the bottom of this stack overflow answer:

I've done this with some success from C code, and it's pretty tidy. Would you be interested in adding such functionality?

Sorry for not getting to this; I don't mind leaving the files around, so I'm not going to work on this, but if you want to then sure.

You can send data to gnuplot without using additional pipes.

cmd "$data << EOD" cmd "0 0 A" cmd "0 1 B" cmd "1 1 C" cmd "1 2 D" cmd "2 2 E" cmd "EOD" cmd "plot $data with labels boxed"
