Managing a projectPlanning with the Gantt chart
Place tasks over time, link them together and follow your milestones on a timeline.
1 min read updated October 2026
The Gantt chart shows each task as a bar on a timeline. It helps you build a realistic schedule and see the impact of a delay.
Reading the Gantt chart
On the left, the task list and its columns; on the right, the timeline. A bar's length matches the task's duration, and its fill its progress.
Changing the schedule
- Move a task — drag its bar along the timeline.
- Change its duration — stretch the edge of the bar.
- Edit directly — title, duration and assignees can be edited in the left-hand columns.
Linking tasks
A dependency means a task can only start once another one is finished. Drag a link from the end of a bar to the next task: if the first one slips, you immediately see the tasks affected.
Milestones
A milestone marks a key deadline (committee, delivery, approval). It is shown as a diamond on the timeline. Reference milestones, defined by your organisation, are highlighted with a halo so they stand out at first glance.
Good to know: the Gantt chart also shows subtasks, to detail a complex task in the schedule.
Frequently asked questions
Is there a Gantt chart for several projects?
Yes: the multi-project Gantt, available in portfolios and on the projects page, shows all schedules on a single timeline.
Does a task without dates appear in the Gantt chart?
It appears in the left-hand list, but without a bar on the timeline until it has dates.
