Why did I only get a part of wave chart even if I have appended the wave together using shift register?

It seems only read 200 samples and then stop. Shouldn't I get a continuous wave chart after using shift register on a while loop?

You must remove Start VI out from the loop...
You cannot 'Start' a task which is already running...

You also remove the Start VI completely from your code... If you do not use Start VI, a measurement task starts automatically when the DAQmx Read VI runs.

Find the attached VI.
