Clear waveform history using reference

[H P]

Hello,

I would like to clean the history of the waveform that I have in my Main Vi. I am passing its reference to a subVi. I am not able to find the History Data property among the other properties of the Property node. Here is that I have:

 Thank you.

If you're passing the reference to the subVI why are you accessing the main VI via the VI Server? Simply use the reference front panel control. Is this a subVI that you're launching dynamically?

And, I think your chart reference is wrong. Did you copy the reference from the main? In your main, have you wired up a data type? Since there is a variety of data that can be wired, you need to do this so the the history is the correct data type.

And what are you trying to do with the True constant wired to the while loop's termination terminal? The loop will only run once.

I was able to get to the Property...

You probably want Invoke Node -> Reinitialize to Default .

I would assume when someone shows using refernces like this, they are showing an example of how they are using the reference in a sub-vi. That's the only thing that makes sense, unless you just like doing things the hard way.
