PHP-based graphing script recommendation

Can anyone recommend a easy to use php-based graphing script? I've been looking at PHPGraphLib but I imagine there tonnes out there. Commerc开发者_JAVA技巧ial or GNU, doesn't matter. Only requirement is image based charts as these will be e-mailed/printed. (no flash)

I've been using jpgraph for some time - it allows you to do all sorts of things with your data. Needless to say this comes at the cost of a little complexity, but it is well documented and includes lots of examples. Its commercial for most purposes, but relatively cheap.

You might also consider Google charts if your needs are very simple.
