The best place to start looking is the examples that ship with LabVIEW. Go to the help menu and select Example Finder. In the search tab search on spreadsheet. Take a look at the Read from Text File.vi and Write to Text File.vi they are good examples to show you how to read data from a tab delimited spreadsheet file and plot the results. Also take a look at some of the Graphs examples.

If it's an Excel file that you need to read and not a tab delimited spreadsheet file then take a look at the NI Report Generation Toolkit. There are some free alternatives out there to read Excel files if you do a bit of searching.

Hi Kurt,

Thank you so much for the suggestion, I think from these examples I can do whatever I want with my files. Thanks again

Why not doing it in C if you are so much more savy with that?

Because my prof asked me to do it in LabView :|

Hi,

I'm a new user of the program (I'm not even sure if I'm posting on the right category) and I really need help on Opening and Plotting my saved points which I acquired from an oscilloscope. I saved my points to an excel file, and as far as I know I must assign these points to an array (if this was in C, I could have done it ages ago, but I'm no good in drag-&-drop programming) and plot them in a waveform graph. Any advice or suggestion related to my question would be really really, greatly appreciated.
