Graphing/plotting software in Linux

[untarnished]

Hi, I was just wondering if there exists an alternative to the graphing program xmgrace, i.e. a WYSIWYG graphing software that runs under Linux and can do everything that Grace 5.1.22 can do (or almost everything; preferably more), and preferably free/open-source? I think xmgrace is good, but it can be improved.

Thanks!

Veusz?
SciDaVis?

Thanks for the suggestions. Veusz looks impressive, I'll surely give that a try.

I also use gnuplot sometimes when xmgrace does not suffice (which is rare). gnuplot is easier to use in batch processes and real time plot updating is also very easy.
