Select data between cursors on a graph

So you want to leave out the white data at the bottom? What should happen if some data is only selected partially?

---

No I want to include the data of all the traces

Do all the traces really have different x-values that are randomly spaced?

---

I don't think the data is random.

It's coming from an array with 9 traces, where the data is stored ,in each iteration, from top to bottom.

I believe that in each iteration, the graph is replotted using the data from this array.

So in a way, it mimics a chart.

How do you want the output of the selection arranged?

---

I want to have an array of all the selected data in an Excel file, with each trace in a separate column and a column for the date and time of each measurement.

So, again, then you don't need the cursor y position at all.

Your full data is a 2D array and all you need to do is taking a 2D array subset based on the two cursors.

Writing a 2D array to file is trivial.

I tried to create a subarray, but it doesn't seem to work.

You need to translate your x values into array indices, of course!

[Alexb91]

Yes that's what was not working.

So I copied the code you used for the integral and tied the cursors to a random plot.

And it worked!
