I have an iPhone app that tracks the price of Bitcoin exchanges and graphs them.
I need to add/change the following features:
> Change refresh rate to every 1.5 seconds (currently set to 0.6 seconds)
> Introduce random error into the current displayed price (add random number between -1.2 and 1.2 to the actual price and display it)
> Change multicolored chart option bar to light blue
> Fix white space underneath graph on iPhone 5
