adding drop lines in Tableau


Drop lines are interactive features that call out the position of marks in the view. This feature comes in handy when presenting views packed with a lot of marks. For example, when you create a scatter plot densely packed with marks, you can turn on the drop lines feature to show the position of each mark when highlighted.
