ctioga2 is a command-line plotting utility. It
enables users to make publication-quality plots of
data and mathematical functions quickly. It is a complete rewrite of the old ctioga, and is much more flexible, with quite a few additional features.

This release adds many new features,
including a powerful styling mechanism which makes it very easy to change the
whole look of a plot with a couple of commands
and makes it simpler to share styles among
several plots.
It also adds more control of legends (including drawing frames around them),
plot axes,
a command for drawing a frame,
and a xcolor.sty-like way to mix colors.
