Oscilloscope Not Mapping to Waveform

I'm trying to get the oscilloscope reading from channel 3 and put it into the waveform V_RECT, but it isn't working for whatever reason. Can anyone help?

The while loop that transfers the oscilloscope reading to the waveform.

Without being able to probe values, the only thing I see that looks suspect is the use of the value property nodes. Any reason you don't use the terminal, or local variable if the terminal is being used elsewhere? In all honesty the value property node should do what you are looking for, but there are ramifications to using them. If you use a property node it will force everything in the enclosing structure into a single thread that is responsible for GUI actions.

I tried updating what I could and it still didn't work. Is there something I missed?

is it possible to probe the waveform before it enters the graph's terminal? I would suspect something about the waveform itself is the issue, not the graph itself. I am willing to bet you have already come to that conclusion yourself.

 

Unfortunatly I am not familiar with the scope or the VI's you are using, wish I could be of more help. Good luck though!
