For my own personal interest work I use PDL and its graphing capability. Chart Director works, we have used it for one client. I have also been a long time user of 'S', and then 'R' so I would endorse those suggestions as well. But like some of the others I wonder what you are after. While the Dundas Charts product has lots of nice tricky eye-candy, does it deliver the underlying data in a usable fashion?
