Did I get it right, you want to read excel data and graph the same data in excel by using LabVIEW?
Or read some excel data, do some LabVIEW and report the result to a excel graph?
Even if I'm addicted to LV and hate VBA, for the first case just turn on the macro recorder , hit alt-F11 do some minor changes and your done.
