I am trying to imposrt a text file with an X and Y column. I want to plot and read only a certain portion of the data, and then measure the baseline to valley. Does anyone know how to do this? I have tried using the "read from spreadsheet file.vi", however was unsucessful.

What exactly were you unsuccesful with? Were you unable to read in the file or plot the data? Once you've read the file, you'll have a 2D array. You can then use index array to get the portion that you want and display it with an xy graph. If you were to post an example of the file or what you've programmed so far, that would go a long way in helping someone understand what else you need to do.
