"Best fit line" is mainly a statistical concept, and CPAN has multiple modules for dealing with statistics. A search on http://search.cpan.org for "best fit" turns up multiple hits, with the first one being the documentation for Statistics::LineFit:
http://search.cpan.org/~randerson/Statistics-LineFit/lib/Statistics/LineFit.pm Using that module or one like it might be able to give you the coordinates you need to add to your GD::Graph graph, but sorting out how to do this will depend on how your overall code has been written. -- Chris Devers DO NOT LEAVE IT IS NOT REAL -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
