I put some notes about Gnuplot here: http://math.cochise.cc.az.us/mtg/basic_gnuplot.html It contains some simple (I hope) instructions on plots, how to get plots into web pages and latex documents, and also how to do linear and quadratic regression with Gnuplot. There are some tutorials here: http://www.duke.edu/~hpgavin/gnuplot.html http://www.cs.uni.edu/Help/gnuplot/ There are some GUIs for gnuplot, but I've never used them. You can read about them here: http://www.gnuplot.org Also, "geg" is nice standalone plotting utility that is very easy to use. It doesn't have all the features of Gnuplot, but sometimes the lack of features is good because it simplifies things. http://www.infolaunch.com/~daveb/ L.
