audio graph UI ( IOS)

I am a programmer, don't have time to finish one task and hence I need someone to do it for me. please check the apple project called speakhere : [login to view URL] In that app they have a UI control that shows the decibel level of the sound being recorded. I need another UI control, to do the same thing, but in a graph, a real live update graph that is continuous and updates as sound keeps being captured.
