I put up a 0.2.0 release of Guile-Charting here: http://wingolog.org/pub/guile-charting/
Guile-Charting is a Guile library to make charts -- bar graphs, scatter plots, and related things. Its web page is here: http://wingolog.org/software/guile-charting/ And the gitorious for git: http://gitorious.org/guile-charting So, remember before computers where you had to draw graphs by hand? Maybe you don't. It was pretty terrible. Painstaking measurements tabulated in graph paper then manually plotted out on log-scales; and if you messed up, or even got new data, you had to do the whole thing again, or bust out the white-out. "Camera-ready copy" and all that. On the other hand, in that olden day, you could make _any kind of graph you wanted_. It was just you and the ruler and the pen. Guile-Charting takes the advantages and disadvantages of both into the age of computer graphics :) On the one hand, you have full control over the graphs, and get to overlay histograms on your bar charts and color your quartiles (or other divisions) as you like. On the other hand, it's a bit rough around the edges and sometimes you have to do things yourself. See the web page for examples of the kinds of things you can do, and the examples/ directory in the source for code to reproduce all of those graphs. I must say, for doing empirical performance work, there's nothing better for me than a Makefile, some CSV, and a guile-charting script. At one point I started doing a grammar-of-graphics R-style charting library. One day I'll get it somewhere useful, but until then guile-charting is my ruler and pen. Happy hacking, Andy -- http://wingolog.org/
