Let me see if I understand you correctly. Basically you are trying to include data acquired from one VI and include it in another. By making your continuous data acquisition VI a sub-VI and placing it on the block diagram of wed.vi you can read data directly from the spreadsheet file. You will want to use the File I/O VIs to read data from the spreadsheet file. These VI can be found in the File I/O function panel by right-clicking on the block diagram and following Functions->All Functions->File I/O. Here is an example that may or may not help:

Thanks! Craig H. ps. Array manipulation may be needed to get the data from each of the four channels to display as desired on the intensity chart. Post again if you have questions about that as well.
