Displaying a measure on a 2D graph like an oscilloscope

An oscilloscope is a type of electronic test instrument that allows the observation of constantly varying signal voltages. Usually, information is shown as a 2-dimensional plot graph of one or more signals as a function of time. In this recipe, you'll implement a type of oscilloscope to display data generated by a background thread. Obviously, in this recipe, you'll not create an accurate oscilloscope; rather, a nice real-world utilization of retrieving data and using it continuously in the GUI.

Getting ready

You'll need to use the TThreadedQueue<Extended> class to bring out data from the background thread to the main thread. The approach is similar...
