. MATHEMATICS: GRAPHING: Gnuplot Many thanks to Sebastien Bacle for providing resource collections for the Russell Conwell Educational Services Center Learning Research and Study Resources Subject Guide. <http://guides.temple.edu/Russell-Conwell-Center> Sebastien Bacle has provided two collections, a collection of general sources and a collection of math sources designed to help students learn and do college level work. <http://guides.temple.edu/aecontent.php?pid=22756&sid=213913> Among the Mathematics sources Sebastien has shared is Gnuplot Gnuplot <http://www.gnuplot.info/> Gnuplot is a portable command-line driven graphing utility for linux, OS/2, MS Windows, OSX, VMS, and many other platforms. The source code is copyrighted but freely distributed (i.e., you don't have to pay for it). It was originally created to allow scientists and students to visualize mathematical functions and data interactively, but has grown to support many non-interactive uses such as web scripting. It is also used as a plotting engine by third-party applications like Octave. Gnuplot has been supported and under active development since 1986. Gnuplot supports many types of plots in either 2D and 3D. It can draw using lines, points, boxes, contours, vector fields, surfaces, and various associated text. It also supports various specialized plot types. Demos here.

Link Topical Organization Gnuplot front-ends Programming interfaces Programming interfaces bidirectional interaction Software that uses gnuplot Web software generating plots by gnuplot Personal pages about gnuplot Other miscellaneous links Content Sample: Software that uses gnuplot Among others...: Octave, a high-level language for numerical computations. Mostly compatible with Matlab. Useful additions (scripts): Reading gnuplot hotkeys: see the section on bi-directional communication above. imagegp.m (version 2006-04-10): a replacement for the default image.m, imagesc.m, and imshow.m, which are fast and support true axes. Requires gnuplot development version 4.1 (uses the plot ... with image plotting style). loadgpbin.m and_savegpbin.m: load and save gnuplot binary matrix files (those from help binary matrix and splot 'x.gpbin' binary). Maxima, a program for symbolic computation. Here are some nice examples of gnuplot output. Mifit, a program to generate assembler code needed to approximate a data set using simple functions. statist is a small and portable statistics program, simple to use and can be run in scripts. Speaking of software, the topic of Powerpoint came up on the Temple Univerisity Listserv based SportPsy list and I contributed this pair of links that should especially interest those who either have qualms about the use of Powerpoint as well as those who are addicted to this tool.
