How to save X and Y vaue from a Waveform Chart

Question

Hello Everyone!
I'm implementing an adquisition systems that send data to a waveform Chart through VISA. All run properly, but I would like to save the data adquired to an excel file. I saw examples to how to save it, but only save the Y value.
I would like getting the X and Y values in 2 columns different in the excel file.
¿Is it possible?
¿Can someone tell me how I can do it?
Thanks for your feedbacks!

I meant uploading the actual VI, not a picture of it. You need to fix your code.
You should not be initializing the serial port in each iteration of the loop. Initialize outside, read in the loop, and close when the loop is done.
Why do you have 2 VISA resource controls? Are you talking to 2 different devices?
The event structure serves no purpose in your code. If you are trying to enable/disable the file writing, use a case structure that's controlled by a simple front panel switch.
You should "remember" the path that the Write to Spreadsheet File uses. Otherwise you will be asked for the filename each and every time you try to save. You can do this using a simple Feedback Node:
Since you are reading the value periodically, just use one of the Get Date/Time functions. You can use the Get Date/Time String to get a formatted string. Then you can format your value as a string, and build your array using those 2 values. Or, you can use the Get Date/Time in Seconds to get a numerical value. Be aware that LabVIEW's starting time is 12:00 a.m., Friday, January 1, 1904, Universal Time [01-01-1904 00:00:00], which is different from Excel.
