matchAppend

Match animation items sequentially: previous item 0 pairs with next item 0, previous item 1 pairs with next item 1, and so on. When the new array is longer, the extra items have no match and animate in from their default position. When the new array is shorter, the ancient items are simply dropped.

This is useful when new data is appended at the end of the array, and you want existing points to stay in place while new points animate in.
