It's very possible, and will look very easy after some "basic training".


On modern versions of LabVIEW you can press  ctrl+space to bring up the quickdrop. Try typing in "read spreadsheet" and "index array" on the block diagram (white side). Try typing in "waveform graph" on front panel (grey side). That should get you started 🙂

Well i hope this isnt a homework problem, but to get you started i would go to the examples built into labview.  Under Help/ find examples.  From there you can look into how to read from a text file.  Fundamentals/file input and output/ text. That will help with reading your text file.  peak through the other examples for more help.


Good luck
