Have you heard of Octave? it is very much like Matlab. (sorry, I can't watch the .mov files you linked to)
Mathematical graphing, etc.

I'm sure openoffice draw can do it. I've just watched the first video. @ mªrty: ubuntu-restricted-extras is all you need (unless you do not want any non-free software on your computer).
qtiplot, grace, labplot are a few of the tools I use.
i vote for the openoffice draw, too. it is relatively easy to use, and it generates vector graphs.
Though, there are other choices such as inkspace, gimp and karbon14, to name a few.
I've moved the thread to Education & Science, you may get additional input here :)
matplotlib is my favourite graphics prog, but maybe geogebra is close to what you want
vrangforestillinger said: For most of my plotting, I use gnuplot. Its commmandline, but the commands are easy to learn. gnuplot is all about plotting, with no mumbojumbo. It can output to just about any format you want, including png, svg or even LaTeX.
I think I've got the hang on gnuplot for what I need; thanks. However, I'm having some trouble with actually getting the graphs into files which I can put into LaTeX documents. I've tried the 'set output "/home/jack/graph.pdf" ' route, but I can't even open the produced file; the same happens if I change the extension to eps. What's going wrong here?

I recommend matplotlib (suggested earlier) more than gnuplot. Its graphs are extremely neat and are of publication quality. Look at the screenshots and example plots here
