A Gantt chart displays project tasks across a timeline. This provides a visual cue on the progress and status of each individual task.
A Gantt chart can help you to organize workloads. Its bars display the statuses and dependencies of project tasks. This reveals the progress of the project, as well as any possible delays or blockers.
To build a Gantt chart, you must display line items on columns when you configure your card. Additionally, the first two columns in your grid should represent the start and end dates for each of the project's tasks. If necessary, hide line items to ensure the start and end dates display side by side.
You can also configure a third column of data, of Date type, to flag key moments of the project for review or reassessment. On the Chart tab, use the Milestone Date toggle on the Data drop-down to turn on this feature. However, ensure your data is in the correct Date format, otherwise it triggers an error message. Additionally, use the Series drop-down to change the Bar Color and the Milestone Color.
On the Context tab you can toggle Hierarchy filters. The hierarchy filter selector displays on the published chart, beside other context selectors for that card on your board or worksheet. Through this, a user can visualize projects and tasks belonging to a specific program, depending on the existing list hierarchy defined in the source model.
On the published page, your milestones display as diamonds. When users click a bar or milestone, any related cards update to display information about the selected task or milestone.
Conditional formatting in Gantt charts
Gantt charts can also use conditional formatting instead of setting bar or milestone colors directly. Gantt charts support conditional formatting as described in Conditional Formatting, and its related procedures.
The conditional formatting is obtained directly from the source's fourth and fifth columns attributes.
Gantt chart interaction
Gantt charts provide an interaction feature that can be enabled or disabled from the card settings. With this, the data displayed by the chart can be adjusted by the user from within the visualization itself. Dragging either bars or milestones, the outcome directly affects the underlying source data. In order to be able to interact with the Gantt charts, you must have the correct authorizations to edit the content in the underlying source. These include:
- access to the model
- access to the module
- write access for any list on which the project is based
- write access in case any dynamic cell access (DCA) has been applied
- enabling the Allow editing toggle in the right-hand configuration panel, under the Series tab.
To adjust content in your Gantt chart, click and drag the start or endpoint of any particular bar, an entire bar, or a milestone.
Remember that any change to the Gantt bars or their milestones will impact the visualization of any chart on the page that shares the same source data.

What can I use Gantt charts for?
Gantt charts have multiple uses. Primarily, they provide an easily-understood roadmap of a project's stages throughout its lifespan. However, they can also help in other contexts, such as trade and promotions planning.
You can also use Gantt charts to improve future releases. For example, you can:
- Assess delays and blockers
- Reassess priorities
- Retrospectively analyze what went wrong
Project tasks on a chart display by bars that span the length of time in which each individual task should take place. This enables you to:
- Visualize a timeline of project-related tasks
- Identify the status and progress of project tasks
- Determine the relationship and dependencies between project tasks
- Identify potential blockers or delays in the project execution
A Gantt chart may not be the best option when you seek further detail about the project tasks, project scope, or resources in use. To identify appropriate options, see Card types.
Anaplan's mobile app does not support Gantt charts.
