    In the market for math-ware

    Anybody here familiar with Sigma-Plot? I'm kind of shopping around for a cheap all around graphing, plotting, computing, type of software that allows me to write math and text simultaneously. Any one got any suggestions. Or, better yet, free downloads?

    Gnuplot is by far the best plotting solution that's open source and free at the same time.

    There is a great support channel on irc.freenode.net #gnuplot aswell.

    I'm having a little trouble downloading this thing. What is it? Is it a plot program? The only thing that i could find to download was some pdf.

    SourceForge.net: gnuplot development: Files

    That should be the correct repository.
    If you're running Windows then gp425win32.zip is the one to get.

    After installing/unzipping you'll find the executables in the /bin directory. To plot a function you can try something like 'plot sin(x)' in the 'gnuplot>' command line.

    OK. I've got gp425win32.zip. Now, how do I use the thing? Which file contains the plotting program? Which file contains the command list?

    Run pgnuplot.exe from the /bin directory to run commands.
    You might need this: http://www.microsoft.com/downloads/d...displaylang=en
    to read help files in Vista/Windows 7. Commands can be looked up by typing 'help' in the command line, or 'help command' to get help on a specific command, try 'help plot'. The files wgnuplplot.exe and wgnuplot-pipes are for piping sdin in Windows. I'm not sure how this works as I'm a GNU/Linux user myself, but pgnuplot.exe should have everything you need.
