Tab Settings/Document Tab Sort Select your field Year and define the sort order After that each chart/table which you create new, will be sorted that way (the sort order will not be changed for existing charts/tables)
You would need to edit each chart and change things on the Sort tab, there is no easy way to do things after the fact as far as I am aware, sorry I do not have better news for you. Using Document Properties\Sheets tab might save you a little time if you know what objects you need to update as you can click properties button once you highlight an object there, but that is about the best I have.
