Do Boosters have any suggestions/experience on how to automate this process, ideally so that a C++ program directly outputs a .png file.
I suggest look at grace. It is a wonderful, free graphing app with high quality output. It can run from the command line, and has various interfaces, such as python interface.

I would concur that grace is a good tool, although I haven't used it enough to know it's quirks. Here's a few of the tools I regularly use to do this sort of stuff: You could look into gnuplot. It's output leaves something to be desired for printed publications, but for online or documentation plots it's not bad. You can still generate your csv files, and write yourself a gnuplot script to automate the production of various file formats (gif, png, jpg, eps, pdf, pnm, etc. etc. etc.) You may also be able to hook into it directly from the c++ if you work hard enough to figure it out ... I've never tried that. You might consider replacing the photoshop step with the ImageMagick toolkit, which can do just about anything to image files that you can think of. You can do your conversion, scaling, and antialiasing in a little commandline script, or through the library. It won't help with the plotting step, however. If you aren't averse to installing a really big package, you could look at the Root framework (root.cern.ch). It isn't exactly the best example of modern C++ best practices, but you can fill out a plot or histogram directly from your C++ library. It's a bit of a steep learning curve, but can make some really pretty plots programmatically. You could even run all your code interactively (I'd compile your library to a so/dll, generate the dictionary, and then load it into the interpreter). I'm sure there are other tools like this that I've used, and if I think of them, I'll let you know. -- ------------------------------------------------------------------------------- Kevin Lynch voice: (617) 353-6025 Physics Department Fax: (617) 353-9393 Boston University office: PRB-361 590 Commonwealth Ave. e-mail: krlynch@bu.edu Boston, MA 02215 USA http://budoe.bu.edu/~krlynch -------------------------------------------------------------------------------
