Due to all the other sub-IV's, I'll have to attach a screen shot.
The read from "Signals Out" is an array of waveforms. That
goes to the property node, fed by a reference to the waveform
graph, and replaces the property of "Value". In this way, the
graphing is handled in a loop external to the main vi, though
I believe it is synched since it is accessing the front panel of
the main vi.
Hope this helps.
