There are a handful of open-flash-charts tutorials on the web, mostly php from what I can see. I know there is a Java helper class, but I haven't found documentation or examples.
The helper library is also includes in the ofcharts grails plugin.
Java/Groovy or Grails suggestions welcome.
thanks!
One of the single best sources I have found on it is here
From the site: "This site is now mainly used to post examples, help and patches for users requesting help in the OFC2 forum which I occassionally haunt."
Has proven invaluable in my developing Java/Grails charts with it. Bear in mind that you need to do little else to make the charts work than to generate JSON. To that end Grails is ideal - however what you will spend a lot of time working on is structuring that JSON data.
The linked site provides the most detailed JSON API documentation that exists for the different chart types OFC supports.
There is also a Java API reference open source project hosted on Google Code:

This is the code embedded in the Grails plugin I've been using so the documentation has helped a ton!
