How do I make specific intervalls on a graph with 2 'dips'

1 view (last 30 days)
I have a list of different graphs that are either straight, straight with a dip, or straight with 2 dips. What i need to do is close in these dips inside an interval IF they exist. The line isn't neccessairly straight but 'vibrates'. I initially just checked if the min value is significantly lower than the max value, but this falls apart if the graph has 2 dips.

islocalmin would do the job! If your data is sharable, I will take a look. You probably need to smooth your data before using islocalmin.
