Here I've added a line to set the visible range with the new selection values. Additionally, I've tweaked the if-statement so that when "No Selection" is selected in the flavor selector the table & chart display the default selection. Previously if the "No Selection" option was selected after viewing a different selection, because `selectionItems` is null there would be no update to the table or chart; now it is really showing "No Selection".
