3.1.3. Peak detection and annotation
A simple peak detection algorithm was implemented to identify a y-value that is greater than its neighbours on either side of a
peak. To reduce the risk of spurious peak detection, a neighbourhood of 26 values is used by default and the peak also has to be
greater than 5% above the average of those values. Depending on the
level of zoom, the number of annotations will increase or decrease
