Graph application tip request

Hi,

as a Mac OS X user I am not into Unix at all. But since it is possible to run Unix application on Mac I am specialy interested in a program making scientifical graphs. There is SigmaPlot for WIN PC�s and this is more or less what I would like to use.
So, here comes the question: is there a good graph app for Unix? Do you know if it�s possibly runnig on a Mac? Where can I get it from?

Thanks for your awncers!!!

Well, I dont know if it will work for macosX but it works for Linux.

because there is the source code, you have to compile it for your platform.

Again I dont know if you can run it on macosX, maybe you need GTK+ or other libray installed before the installation.

Good Luck !!!

And if you are looking for third-party software - Prism is comparable to SigmaPlot.

Prism is about what I am looking for... although a tad expensive. There is also DeltaGraph but...$
