I'm relatively new to LabView, only having use the program for 3 weeks now. I'm working on a project that involves taking multiple data sets, averaging them out to reduce error, and then displaying the results of the processing. The program already collects data and places it into an array, but it is doing this inside of a loop and so it writes a new array every time. I want to be able to set it so that after a button is pressed, the array is used to start writing on a spreadsheet then waits for new data, then writes that to the same spreadsheet under a a new tab, then does so for as long as the user asks it to. I'm not sure how to go about this without it wanting to write a new spreadsheet each time and would appreciate any ideas or suggestions.
