Data being collected does not look as expected? Can someone please help?

I'm going to jump in off topic but addressing some disturbing observations of your code.

You have configured a finite Task for exactly 1000 points at 1000 samples per second.  Then you stuck the read in a loop!  Worse, you added a wait 200msec function in the loop that cannot complete until 1 second worth of samples have been acquired. This is not ideal.

Thanks a lot @Mr.Altenbach and @ROtakecandad

It worked as expected.

Thanks Mr. Altenbach for the explanation.
