What Is The Right Algorithm To Detect Segmentations Of A Line Chart?

To be concrete, given 2D numerical data as is shown as line plots below. There are peaks on a background average movement (with small vibrations). We want to find the values of pai

Solution 1:

Note that this is not an exact answer.

I seriously have no idea what you are trying to do. But I can suggest you a way. Assuming that there is only one peak in the graph and you have all the 2D points data i.e; (X1,Y1)...(Xn,Yn)...

Try calculating the differences between the Y values of adjacent points and get the minimum value if you are doing Y_n-1 - Y_n (which indicates starting point of the peak). Similarly, get the maximum value which indicates the points with the decreasing peak.
