Re: Charting API?

One other library worth keeping an eye on is QWT
(http://qwt.sourceforge.net/). It's a very impressive 2D and 3D
plotting library for Trolltech's qt. There is a qt for mac, but it's
Carbon based so I don't think it's practical to use QWT with Cocoa,
but Trolltech is investigating migrating Qt-Mac to Cocoa (because of
the lack of 64-bit support in Carbon) at which point, QWT would become
pretty awesome.
