You could always just add a Functions->Numeric-> Increment (+1) to the output to up the index.
Alternatively, leave the zero index as a blank value, set index=1 as your first case, then set the Data Range to have a minimum of 1.
I don't think in LV you can bypass the zero index of the ring (wasn't it available in CVI or LWin though?).
