It will almost certainly be simpler to work this out from the data, rather than trying to mess around with a chart control.

But since you haven't told us which chart control you're using, what type of application you're writing, or where the data comes from, any answer you get will be pure guesswork.

Start with a sheet of paper and a pencil.
Solve the problem by hand, repeat with other datasets.
You follow a method, write down the steps and try to solve the problem by following mechanically the method, if it don't work, refine and try again.
At the end, the refined method is your algorithm, just translate to code.

We have no idea what is your mathematical background, your programming knowledge, what your have already tried.

Solution 2

If the sampling rate is the same for both series, they will intersect where the x and y values (i.e. sample points) from both series match. If only one matches, that works too if it's not an end point or running parallel.
