You aren't passing anything out of the while loop. In your 'Selected' event, you have the exit tunnel set to Use Default if Unwired. That means an empty array and when the Stop event is executed, that is what you get. You've also got the Stop function in that event and that is just plain wrong. Even if you had data, you are aborting the VI.

Why dont' you use a shift register?

Actually im not sure of how to do. Do you have any example/ can you help me edit the block diagram? As i'm really new to LabVIEW.

You already have a couple of shift registers. Just create another in the same way.

I tried. but still the same. do I have to recreate a block diagram? or adding a shift register in which particular loop?

I managed to get the graph, but why will the scale go two times? Can someone help to verify my problem? Thank you.

And also can someone teach me how to use the stop function?
