Release Notes: This release added the ability to set symbol size according to a Z column and its color with another in parametric plots, and full control of depth and elements that extend beyond the plot boundaries. It also features quite a few usability improvements and bugfixes.
Release Notes: This release fixed two annoying bugs, including one that affected Windows users using accented characters (or other local characters) in file names. Upgrading is recommended.
Release Notes: This release adds the ability to run smoothly on Windows computers, including many usability fixes on Windows. It provides richer ways to fill curves, a new impulses plot style, and much more control over the appearance and exact label of ticks. The Web site was greatly improved, and now features a gnuplot versus ctioga2 gallery and a graphical index meant to easily find the code for features.
Release Notes: This release brings in several new features, including a simpler command file format (the old one is still supported), contour plots, multicolumn legends, and much better error reporting. It features a number of less important improvements, such as a better control on legends and on axes, increased tick label size by default, and various bugfixes.
Release Notes: 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.
Release Notes: This releases fixes a few small but annoying bugs concerning legends. Online documentation was also updated.
Release Notes: ctioga2 is a complete rewrite of ctioga, avoiding the mistakes made in the original design. It is much more flexible and powerful than the old ctioga. It features most of what the old ctioga could do, but it also supports plots of 3D data (XYZ color maps, for instance) and contour plots. All users of ctioga are encouraged to switch to ctioga2. Development of the old ctioga has stopped.
Release Notes: This version brings much better control over the look of the legend, including a much simpler scheme for positioning, frames, background color and transparency, legend lines unrelated to plots, and control over the height of the lines. In addition, the text data-gathering backend was improved to be able to split text files into subsets at blank lines (a bit like in gnuplot). There are many more small feature enhancements and small bugfixes.
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.
