Hello, I want to receive x and y values of a graph every second and save them in a new text file. How can I create this?

After creating an array, I'm not sure what to do next.

You only need one loop, I would use the first FOR loop.

Create a 2D array from your plot data and write that 2D array with a WriteDelimitedFile function. Use "append"-mode if required...

 

Do you know we cannot edit/debug/run images with LabVIEW?

Best regards,

Thank you, sir

 

I made it like this, but there is an issue with the text file. The x-values should be in the first column and the y-values in the second column, but the results appear to be  incorrect.vi.PNGtext.PNG

Just transpose your array, that is:

Hi,

 

read the help for the WriteDelimitedFile function!

There is an input named "Transpose?"...

Best regards,
