Issue Details

I am trying to pass waveform data into a waveform chart property node. It is only allowing me to pass variant data. How do I fix this?


This is because property nodes, by default, don't know what data type you want to pass into it. You can let it know what type it is by creating a strict property node.
You do this by:
  1. Making sure your chart is of waveform data (pass waveform data into the indicator).
  2. Create a control refnum.
  3. Place the chart into the control refnum.
  4. wire that control refnum into property node, and see it add the word "(strict)".
  5. Now you can pass waveform data type into it.
