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.

A 'gnuplot' backend was added to extract data from gnuplot input files (but only data); several new filters were added to modify data on the fly. This release also features several bugfixes and minor improvements, such as better handling of log scale for mathematical functions, via the --math-log option, offsets for X and Y axes, and more.
The legend position is now much more like what it was for releases 1.5 and before. An option has been added for direct PNG output (depends on ImageMagick), as well as a way to create shortcuts for series of command line arguments and a way to simplify grid and column plots (with automatic insertion of --next arguments).
This release brings in fixes for very annoying bugs (--grid looks better, and --text-baseline works again), and some new features to gain better control over curves styles, along with their documentation.
This version brings in many new features, such as
a way to fill regions between curves, grids of
plots, plots with alternate axes, columns of plots
sharing the same X axis, a new layout system
(making manual adjustment unnecessary in most
cases), and many more usability fixes.
This release adds filled curves, transparency (for fills, curves, error bars, and markers), a very simple way to create an inset with a zoom in (or zoom out) on an already existing curve, and much better looking histograms.
