How to find the coordinate of a peak from a dataset
I have a data group.
This is the graph I am plotting using this dataset.
How do I find the coordinate of the peak value from this dataset? Anyone got a good Java algorithm for this issue?

For this dataset, I would do the following:
- Make the data stationary while accepting the first differences
- Signal when data exceeds a certain threshold level. You can use fixed threshold or adaptive threshold (like this answer )
When I use the dataset from this question , for illustration purposes, I get the following in Excel:
It should be easy to implement in Java.
Good luck!
