Do you change project settings?

1. Copy the CorePlotHeaders directory to your Xcode project
2. Copy the Core Plot library to your Xcode project.
3. Open your apps Target Build Settings, and for Other Linker Flags include this: -ObjC -all_load
4. Add the QuartzCore framework to the project.
5. Change your C/C++ Compiler in the project build settings to LLVM GCC 4.2 or LLVM 1.6.
