gnuplot

[Martin Czech]

gnuplot is a very nice tool for visualising data and formula etc.
I don't need to explain why some thing like this is very usefull for 
diy, ok ?

And it's free. Does anybody know if there is a windooze version ?

I have checked http://www.cs.dartmouth.edu/gnuplot_info.html
but there's only a dos version in protected mode, I fear.

Is there anything else free and comparable ?
