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 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 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.
