Phil, >I'm looking for a graphing program that produces publication-quality graphs I use R for all my graphs (and most of my statistical analyses as well). R is essentially a programming language that has statistics functions built into it, so you don't need to write code to calculate a standard deviation or other commonly used functions. It has many built-in graph types, and you can create new graph types from scratch. It also gives you control over every element of a graph, such as the axes, plot symbols, shading, colors, angle of lighting for 3D graphs, etc. Pros: It's extremely powerful and flexible, runs on most platforms, and is free (see http://www.r-project.org). It's the software most academic statisticians use, so there is a large user community that contributes code and packages. Cons: Somewhat steep learning curve, online help isn't always useful Good luck, Steve -- -------------------------------------------------------- Steve C.
