The visual allows you to highlight changes between elements as arrows at the side:
Highlighting in general can be toggled by the highlights button in the menu:
When you open the menu, you have the predefined choice of Min/Max and First/Last. They can be toggle independently.
If you wish to add highlights between other elements, you can create them with Add New. A window will appear and you will be asked to select two elements one after the other. After adding a new highlight, an entry will appear in the menu, which allows you to remove the custom highlight.
