For drawing graphs you can have a look at google graph api (http://code.google.com/apis/chart/) I've once used another cart libray offering API in different languages see : http://www.advsofteng.com/product.html And then there is GD::Graph, but I have no experience with this. For basic graphic functions look at Imager (imager.perl.org) -- Regards Rolf Schaufelberger
