Hey siktigit ys,

There are built in Least Square Fit functions in LabVIEW. Here is some information about them. If you are having trouble reading the data from the file, here is an example showing how to use the read and write VIs. In order to show your data in a graph, I'd just read the data from the text files into an array and display that array on an XY graph. That should be enough to get you started. If you need more help, just let me know and have a great weekend!
