show graph that is created in a subvi

[monglebest]

Hi,

We use the Labview 2012 but the two level VI reference doesn't work for our case. We download the the example but it cannot display the 3rd level subVI's graph in the first level in real-time.

The VI reference can display information from 3rd level VI to 2nd Level VI simultaneous, but when the VI reference is created from 2nd level VI to 1st level VI, there is no real-time update. What we need is a real-time update from level-3 to level 1.

We have tried to use global variable but it does't work.

Any one works out the 3 levels real time display?

Hi,

I tried the same method as described to show a graph on the main VI. But my subVI gets much slower because of this. Is this normal?

Best regards

Hi KF,

This is expected behavior. The property nodes used in the SubVI will hurt the execution time of the sub VI.
