Hi,

Try xmgr.  You can find their web page at:

http://plasma-gate.weizmann.ac.il/Xmgr/

Some features (from their web page)

A few of features of ACE/gr are: 

     User defined scaling, tick marks, labels, symbols, line styles,
	colors. 

     Batch mode for unattended plotting. 

     Read and write parameters used during a session. 

     Regressions, splines, running averages, DFT/FFT,
	cross/auto-correlation, ... 

Note the last one!  :-)

It now comes ready to work w/ xbae which, as I understand it, works much
like a spreadsheet.  I can't find xbae's web page right now - it's out
there somewhere.  :-)

Also, xmgr is in the ports - /usr/ports/math/xmgr!  I've used it recently
to do a bunch of figures for a published paper and will use it for my
thesis. 

Hope this helps.

Brett
