I dont know how to manupulate and change the time scaling for my amplitude plot chart so that it can plot the value of my amplitude every 1 minute or 30 seconds not like every few milliseconds.i upload the simulated VI.
If you don't want to sample so often, then use a Wait (ms), Delay, or even an Elapsed Time function (with your existing code inside a case statement and wire the case selector to the Time Has Elapsed output).
