Thanks Bob!
In the end it seems I was trying to over-complicate it.
To sum up the solution for future readers;
-Use shift registers to allow the graph to behave like a chart
-Bundle your signals into clusters
-Build those Clusters into a single array, then wire that array to the Waveform Graph
-Remember to initialize your shift registers to 0, to clear the previous data
Thanks to everyone who posted as well, Happy Holidays~
