Real time graphing in app inventor

[Skyler]

Disclaimer: If a graphing library exists that can easily do what I am trying to do I would be more than happy to switch to that so that would similarly resolve this for me. 

I am currently working on graphing data that I am receiving in real time and for now I have this test block that graphs a generated sine wave. Eventually I am intending to replace that with a poll to a current variable value. For now though the graph clears everything and swipes back to left to start drawing more lines. Is there any simple way I can shift the graph once it reaches the far right such that the oldest elements get truncated out. Whatever method I implement needs to work in far excess of the view window time period so the methods that came to mind seemed like they would cause a memory leak.

This thread discusses two ways to possibly do what you want with a graph   One uses a graphic library which may require an Internet connection (or perhaps not), the other displays a continuous 

waveform using native blocks.  It starts a new trace after a set limit of monitoring.  Either solution might be suitable for what you are attempting.
