Recognition of dynamic reference lines

[Rainerr]

Hello everyone,

It is about a geometric measurement with the help of reference lines.

The attached picture shows a part of the data set, this is a picture of about 3000 continuous graphs.
As these data pass through, the values, the complete graph, moves along the X and Y axis (due to measurement not being ideally centered). The graph in the green area should be measured.

To be able to measure the geometry clearly, I thought of dynamic reference lines, the red lines, from which the values can be determined.

But I have not yet found a function to detect these lines clearly and use them for further calculations.

I hope you have an idea:)
Many thanks in advance!
