How can I delay the t0 of a waveform based on user input without affecting the start of another waveform in the while loop?

[westerman111]

I would like the waveform generated with the waveform builder to wait until the user presses a button to start. I have tried implementing this with a case structure, but have not succeeded. The problem is that I do not know what to make the case output for when the user has not yet pressed the button.

Consider using event structure instead of case structure. So move the waveform builder into the event structure, so that it will be executed when an event like mouse click happens. http://zone.ni.com/reference/en-XX/help/371361J-01/glang/event_structure/
