Release Notes: This release has seen progress in many domains. You can now draw PNG or JPEG images in graphs. Text labels (title and axes) can now be auto sized (i.e. the will be as large as needed to fill the side of the graph). You can now include inline Ruby code in command files to make it easy to define functions (for math or data processing). Color map specification has been extended which, combined with the inclusion of color sets from colorbrewer2.org, makes it easy to draw meaningful heat maps in a simple way. Of course, this release brings in its load of bugfixes and minor updates.
Release Notes: This version brings in quite a few new features, including functions that can be used to get information from already loaded datasets and perform various computations, more control on axis ticks, and multi-line titles and axis labels, along with quite a few bugfixes. More importantly, this release includes a new script, ct2-make-movie, that makes the construction of movies fairly straightforward: if you know how to make one of the graphs you need, you turn that into a movie.
Release Notes: This release brings in histograms. Using the new histogram plot style, it is possible to draw series of plain histograms along with stacked (or cumulative) histograms. This version also contains bugfixes and various improvements, including the ability to use xcolor-style color mixing not only with colors, but also with colorsets (useful for colors used for filling, for instance).
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 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: 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.
