Retrieving Data from AudioKit's FFT Plot

I'm working on a project that involves recording audio from the microphone of the iPhone, then feeds it through a Fast Fourier Transform (FFT).

I've found AudioKit.io has a demo in which it actively monitors microphone input and can display a plot of the FFT.

I have equations and logarithms that I plan to analyze the audio data with, so all I really need help with is retrieving the FFT data that is sent to this plot in AudioKit. I'm having a hard time finding the functions/methods that drive the data that fills this plot.

Can anyone point out where to find this FFT data in AudioKit?

The FFT code that AudioKit uses is pretty standard. You could take AudioKit's Plot and reappropriate the code as you wish:
