How to update values outside while loop

[uwm]

The LabView updates a waveform graph every 0.1 sec.

When a user presses a button, I want LabVIEW to wait for 5 sec and play a sound for 5 sec.

Meanwhile, the wavefrorm graph should be continuously updated. 

When I have the case structure inside the while loop, it interferes with waveform graph updates. 

When I have the case structure outside the while loop, the case structure is never executed. 

What can I do?

Start by taking the tutorials on LabVIEW to turn about dataflow.

Your other structure cannot execute until the while loop ends because it has a data dependency of the boolean control.

I have figured it out by using the Producer/Consumer Design Pattern example.

It allows a variable that is updated within a while loop to be updated outside the while loop while the loop is running.
