You can display lines that show dependencies between all nodes.
Before you begin: If the Gantt chart is currently displaying the dependencies
of a specific node, hide them. For more information, see
Hide Links below.
From the Gantt chart header, select .
Dotted lines are displayed between all dependent nodes. Each
dotted line ends with an arrow that points toward the node that represents the object that
has the highest position in the hierarchical structure. Passive links (corresponding to
passive tasks in Project Management) are also displayed. For example, consider a task that
has a subtask. In this case, the dotted line between the task and the subtask ends with an
arrow that points toward the task.
