sub-VI and main VI

[analog]

My main VI calls a sub-VI. I used the get control value (variant) to get the graph in the sub-VI, and output it to the main VI in a cluster. I set the maximum y scale in my sub VI, and it works. But when I get the graph in the main VI, my maximum y scale doesn't look right. Shouldn't I get the same graph that I got from my sub-VI. Is there a way to fix this? Thanks

Yes, put the graph on Main vi and pipe the data to it via a reference.

Hm....but I am using the open VI reference method so that I can control the main VI while the sub-VI is running. When I tried to send the reference to the sub-VI and sets it. The graph just goes blank after every is done.

The Get Control Value function just returns the value, not the other
properties. Other postings point out what you probably want to do.

I tried to send in the controls of my cluster to the sub-VI and set the property from there, but somehow, everytime my sub-VI is done running, everything just went back to default. My whole graph is gone with nothing on it.
