One additional that your other responses didn't touch on is that if you save your data with a LV timestamp for each sample (you know: the number of seconds since midnight GMT 1904) you can do some really neat things when you go to plot the data.
For example, assuming a file structure where each row contains one set of readings and the first value is your timestamp, read the whole file using one of the techniques the other posters have given. The result will be a 2D array of floating point values. Now extract the column of data containing the timestamps and use it for the X axis of an XY plot. Now, on the front panel, right-click on the graph's horizontal axis and select "Formatting...". In the resulting dialog box select "Time & Date" on the Format popup
menu and click OK.
Now when you plot whatever other columns of data you want, they will be shown relative to the time and date they were collected. Very Cool...
