Extract data from a FOTK AudioKit graph

I am working on a project that involves recording sound from an iPhone microphone and then transfers it through the Fast Fourier Transform (FFT).

I found AudioKit.io has a demo in which it actively controls the microphone input and can display the FFT graph.

I have equations and logarithms with which I am going to analyze audio data, so all I really need is to receive FFT data that is sent to this section in AudioKit. I find it difficult to find functions / methods that manage the data that fill this plot.

Can someone please indicate where to find this FFT data in AudioKit?

The FFT code that AudioKit uses is pretty standard. You can take AudioKit Plot and change the code as you wish:
