Looking for graphing software, right place?

[rocomath]

I remember using this program called "Carbi-Geometry" or at least I think that was the name. I googled for it today and it's not free "anymore" unless I'm confusing the name.

I want to be able to graph not only triangles, but graphs as well, and I need to be able to label things.

Thanks!

You can do a fair bit of graphing with just Excel. Is that sufficient for what you need now?

Cabri?

From googling Cabri and freeware
I found http://oisteing.wordpress.com/tag/freeware/

Do you require the dynamical-geometry features?
Or are you just trying to draw geometrical figures (with lines and points)?

Gnuplot can plot graphs: http://www.gnuplot.info/
Asymptote can do some interesting things: http://asymptote.sourceforge.net/
There's also http://www.xfig.org/ and http://jpicedt.sourceforge.net/ and probably a lot more depending on what you really need it to do.

I 2nd gnuplot. It's pretty cool.

I don't have Excel :( I have "OpenOffice" since I'm broke!

I would like someone that can graph triangles & functions and that will allow me to label whatever I want. I'll check out the Cabri link you found, it's not loading on the school comp so I have to wait till I'm home.

I think I have gnuplot, but I don't remember being able to label on it.

Ok, the link works on this comp! GEOGEBRA! haha, not Cabri :) Thanks!

Although you've found what you were looking for, if you weren't satisfied with gnuplot, xmgrace offers a lot of the functionality that gnuplot lacks.
