Gantt View
The Gantt view is available in The One Projects. This page documents the planned behavior and interface. Check your Projects version for availability.
The Gantt view provides a horizontal timeline visualization of a project's milestones and tasks, showing planned start and end dates, dependencies, and current status at a glance. It is the fastest way to communicate project schedule to stakeholders.
Accessing the Gantt View
From any project, click the Gantt button in the project header (alongside Board, Milestones, Time, Documents, and Team tabs).
Reading the Gantt Chart
The Gantt chart displays:
- Rows — One row per milestone, with tasks nested beneath it
- Horizontal bars — Each bar spans the task or milestone's start date to due date
- Color coding — Bar color reflects status:
- Gray — Pending / Not started
- Blue — In Progress
- Green — Completed
- Red — Overdue
- Orange — At risk (due soon, incomplete)
- Dependency arrows — Arrows connect tasks that have a dependency relationship. An arrow from Task A to Task B means Task B cannot start until Task A is done.
- Today line — A vertical dashed line marks today's date, making it easy to see what is behind schedule
Navigating the Timeline
| Action | How To |
|---|---|
| Zoom in / out | Use the zoom controls in the header to switch between Day, Week, Month, and Quarter views |
| Scroll | Drag horizontally to move forward or backward in time |
| Jump to today | Click the Today button to center the view on the current date |
Drag to Reschedule
To adjust a task or milestone's dates:
- Hover over a bar until the resize cursor appears on the right edge
- Drag right to extend the due date, left to shorten it
- Drag the middle of the bar to shift both start and due date together
Changes take effect immediately and update the task or milestone record. Team members see the updated dates in the kanban board and Milestones tab.
Dragging a task that has dependent tasks will not automatically cascade the date changes to those dependents. You must update each dependent task separately.
Critical Path
When critical path is enabled (toggle in the Gantt header), the chart highlights the sequence of milestones and tasks where any delay will delay the overall project end date. Critical path items are shown with a red outline on their bars.
Use critical path to quickly identify which tasks need prioritization to keep the project on schedule.
Exporting the Gantt Chart
Click Export in the Gantt header to download the chart:
- PNG — High-resolution image suitable for slide decks and emails
- PDF — Paginated document with project name, date range, and legend
Exports include all visible milestones and tasks for the current zoom level and date range.
Tips
- Use the Month zoom for executive reporting — The month view shows the full project arc without too much detail
- Use the Week zoom for sprint planning — Individual task bars are readable at the week level
- Export to PNG for client updates — A Gantt screenshot in an email or slide deck is easier for clients to understand than a link to the portal
- Check critical path before committing to a deadline — If the critical path extends past your due date, you need to compress scope or negotiate the deadline
