last item in list of unequal points

I have a pretty simple question and im having a little bit of trouble. I have vertical lines which are divided by distance, each vertical line is a different length yielding a different amount of division points. I need to retrieve the last or bottom point on each vertical line.

Usually I just reverse the list and select item 0 but that is not working. I have seen a few posts on the subject but i still cant seem to figure it out. I might need to use the path mapper but i havent used it much.

Hi Charles,

Firstly, because your flipped lists have the same data structures, when they are merged the lists combine to be two columns in one list so the last item would only show up on every other column.

Secondly, there are null values in your lists and more often than not they are the last item therefore are not showing up.

Pass your lists through a clean component before reversing it. this should do the trick.
