G'day Nigel, All. Another charting package that I've just started using is Chart Director[1]. It creates beautiful graphs and charts and is very flexible. It's not free but it's relatively cheap and you can download a free version that watermarks your charts if you want to test it out.
Supports Windows, Linux, Solaris, FreeBSD, OSX, ASP, .NET, Java, ColdFusion, PHP, Perl, Python, Ruby, C++, 32bit and 64bit. Phew!
