[Techtalk] Linux graphing program

[Caroline Johnston]

Hi,

How complicated are your plots and equations? You could try R (Stats 
package like Splus (actually almost identical) or Matlab) 
http://www.r-project.org/ which has pretty good graphics capabilities and 
is free. Little bit of a learning curve, but it's quite a handy thing to 
know. Might be overkill though!

Also, maybe have a look at the http://www.astro.caltech.edu/~tjp/pgplot/, 
they've got a list of interactive drawing programs that use the PGPLOT 
library.

Hope this is some help, 
Cass.
