If I have used the create list of points from the spreadsheet, and subsequently want to add inputs down the spreadsheet column, what script can help to add points to the ones already plotted without deleting or double plotting the old and new points?
The same question 
Thanks, I have temporarily solved it by pre assigning 30 points from A1: B30 .While points P_{12} to P_{30} are not plotted when cells A12:B30 are empty, they will automatically plot when pairs of values are input into the cells!
