A Gantt chart displays phases on the line level that are divided up into rows. These rows contain tasks or milestones.
Phases and rows can be renamed, moved according to requirement, and phase arrows can be hidden, revealed or deleted. You can add a new task or milestone to every row. To do so, hover over the row until a +-symbol appears and then select either to add a Task or a Milestone. Your project plan will then update in accordance to your settings.
In addition, you are able to enlarge or shrink the region in which phase and line labels are displayed. To do so, move your cursor to the right of the region until a bilateral arrow. You can then adjust the width of this section while holding the left mouse button.
