I have a graph and need to the find minimum points, how can I do that in LabVIEW ?

Solution

In order to find the minimum points of a graph, you can use the Peak Detector function. To find the function right click on LabVIEW block diagram > Signal Processing > Signal Operation > select Peak Detector. Then, set the threshold value of the graph and change the function to find valleys, please have a look at the picture below :
The result below show the total minimum points found and minimum points amplitude below the threshold value :
