hai shrekt, i've tried to modifeid your VI sent earlier for me to save the table data and to read it back. it works partially but on the graphs where it reads the data.

The problem is, it also create a reading/data that is unknown making me hard to read my own data on the graph. do you have any idea on it?

Hi,
1. the vi you sent automatically record all rms number that appear into the table, where as my idea is we can select which rms we want to be recorded into the table.

2. refer to the picture below, the 'saved data' graph gives us to lines where the red line is the real reading while the blue line is unknown. as the blue line is constant at 2, it does make me hard to read my real data because the RMS i want to record are just aroung 0.002. how can we get only 1 line in the saved data graph, that reads the data table.
