Thank you, Martyn; I was not aware of this.

I'm looking to measure 16 channels (two TC-08's) every 100 milliseconds, but the only code I have found in the following places show how to make a single measurement with no option for measuring all at once; measuring single in a loop is not acceptable in my case: - this forum thread's user-uploaded...

Can confirm minimizing then maximizing fixes graph rendering. Also works when the graph is all-black (like, a black screen instead of a grid, which happens after computer goes to sleep and is logged into again)
