Release Notes: This release has many new features, such as a comfortable way to organize several different plots on one object, the ability to make free-form graphs, and much more control in the look of axes, including the ability to display axes with a non-linear mapping. Several bugs have been fixed.
Release Notes: 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.
Release Notes: 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).
Release Notes: 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.
Release Notes: 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.
Release Notes: 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.
Release Notes: Many major features were added: error bars, themes, much better control over legend position, insets, parsing of CSV files, transparent file decompression, histograms, and much better control over presentation details in general. This release makes ctioga really suitable for most 2D scientific plots.
Release Notes: Ctioga now supports color gradients for successive curves, the ability to add (nearly) arbitrary graphics primitives, tangents to curves, and much more. Support for graph size and margins was made easier.
Release Notes: This is the first really functional release. It is now possible to make PDFs of an arbitrary size, ready for inclusion in any kind of document.
