Definition

What is Gantt chart?

A Gantt chart is a horizontal bar chart that lays out a project's tasks against a timeline, showing start and end dates, durations, and how tasks depend on one another.

A Gantt chart turns a schedule into a picture. Each task is a bar whose position and length show when it starts, how long it runs, and when it ends. Lines between bars show dependencies.

Gantt charts are best for projects with a clear sequence and hard deadlines. They make it easy to spot the critical path, see overlaps, and understand how a slip in one task pushes the ones that follow.

Atlas offers a timeline (Gantt) view of any project, with editable dates and dependencies, so a plan can be dragged into shape and instantly reflected in every other view.

FAQ

Questions, answered.

What is a Gantt chart used for?
Gantt charts are used to plan and communicate project schedules - showing task durations, sequence, dependencies, and deadlines on a single timeline view.
What is the critical path on a Gantt chart?
The critical path is the longest chain of dependent tasks that determines the earliest a project can finish. Any delay on the critical path delays the whole project.
