gnuplot (http://www.gnuplot.info) can probably do what you want.
I've been using it since the late 1980s and am quite happy with it.

There's an OpenBSD port (/usr/ports/math/gnuplot/), or you can fetch
the official source distribution from the gnuplot web page and compile
it yourself.  The Development sources from SourceForge also build fine
on OpenBSD.

ciao,
