There are tons of good graphing programs. The difficult part is to get the data into a usable format. Excel has some good graphing features, but it's somwhat limited in extras. My favorite (though, in my experience, one of the most difficult to use) program is SPSS Science SigmaPlot. If you want something to graph data *very* easily, check out MINITAB. You can't get any easier than that program.
Edit: By the way, as far as I know, you need 3rd party packages to generate such graphs in Excel. They can be generated automatically by SigmaPlot, though, as I said, getting the data will be a little difficult. Also, if you do so in SigmaPlot, you have a number of options which will allow you to customize dimensions, colors, etc.

GNU Octave is a good freeware numerical analysis tool, although it is a programming language that you'd have to learn. You can implement C/C++, Fortran or others with it. It's mostly compatible with MATLAB if you've ever used that.
