Digital waveform transitions

[Zwired1]

Can someone please explain why my "transitions" array is empty in the attached?  I would expect a transition to be the index into the array where the nibble (in this case) at that point is different than the previous value.  For the attached, this should be every index, I would think.  But it's not....

It's just a fancy cluster. If you open the ramp VI, you'll see transitions is not set.

You need to compress the signal. Then the duplicate data will be removed and the transitions are set.
