How to built a graph using only max values from DAQ?

Go to solution



I am trying to built a graph using only max values that I adquiere from my DAQ USB6001. The problem is that the values from my DAQ are not always going up, example: (0,4,8,6,5,4,9,...) and what I want to do is: (0,4,8,8,8,8,9) so I replace other values with the previous max value.

For this I tried to use shift register with 8 continuous comparison (using greater or equal), for 8 iterations it works but the max value is not saved and it changes after the 8 iterations.

How can I save the max value? So I can also compare that value with the new ones coming from DAQ?



I'll apreciate any feedback, thanks 😄

Pd: I know my vi is a disaster, my bad.

Hi Jorge,


why do you need so many shiftregisters?


Just one feedbacknode/shiftregister will do:

Hi GerdW,


I used many shiftregisters because I tried to solve my problem manually.


Anyway, your solution works perfectly. Thanks.


Best regards
