I would not recommend OFC. The project is ostensibly dead. I used it extensively in my own site for charting, and found it a pain. I just finished removing all of it so that the site is iPad friendly.
  • OFC has not been updated since 2009.
  • There are plenty of bugs only maintained by their public forum.
  • The documentation is sparse and a number of the examples/features don't actually work.
  • The SWF is large and loads slower than competing libraries.
I had to learn some AS3 myself and recompile the source to get basic things like Fullscreen to work. Since no one is officially maintaining the project, you'll have to download the source and apply the public patches and rebuild yourself.

I would suggest the all JS charting library HighCharts, or the Google Visualization API, both of which are under active development and have GWT wrapper libraries (HighCharts, GV). You can start with OFC, but you will have to fix many problems yourself from the start.


Sincerely,
Joseph
