I've converted my project to iOS 5 and enabled ARC. Now I need to integrate core plot with the project. When I try to instantiate a sample controller included with the Core Plot, I get about 20 errors as follows:

I've explicitly said **`fno-objc-arc`** next to the controller's name in the build settings. 

What else do I need to run core plot with ARC enabled?

Thank you!
