Every Gantt chart consists of two parts:

  • Work breakdown structure, which defines the scope of work and is built using Structure functionality
  • The chart itself, which visualizes your tasks on the timeline, showing their start and finish dates, dependencies between them and other information

Structure and Gantt

This guide assumes you already have a working knowledge of Structure - if not, check out Getting Started with Structure Cloud. The following sections will cover those elements specific to Structure.Gantt.


Using the toolbar, you can:

  • Access Gantt Configuration Settings
  • Show/hide resources
  • Adjust the chart's appearance
  • Select which elements are shown within your timeline
  • Create dependencies
  • Turn tasks into milestones

Gantt toolbar


Your timeline contains visual representations of tasks, dependencies, milestones and other key dates. It is also where you will do most of your work. You can adjust tasks and dependencies directly from your timeline.

Time Scale

You can quickly navigate or focus your timeline in a variety of ways:

  • Zoom in or out to see more or less of your timeline
  • Scroll horizontally or vertically
  • Focus in on the current date with the Today button
  • Navigate to the current task with the Scroll to Task button (only appears if the currently-selected task is not visible)

Navigating the Gantt timeline

Start Day and Current Date

The project start date is indicated by a green vertical line. The current date/time is indicated by an orange vertical line.

Mousing over the point at the top of either line will display the exact date.

Start Day and Today's Date

Task Bars

Structure items are represented in the chart as task bars.

  • A task's position on the timeline is based either on its dependencies or on manually-set Start and/or Finish dates.
  • If a task is part of the critical path, it is shown in red. The rest of the tasks are blue. You can show or hide critical path highlighting using the Options menu in the Gantt toolbar.

Task Details Panel

Clicking a task bar will display the Task Details panel, which contains information about the task's scheduling and resources. 

Task Details Panel

For more information, see Task Details Panel.


If an element has children in a structure, it can be shown as a Group.

  • A group's Start Date and Duration are calculated automatically, based on the Start Date and Duration of the elements it contains.
  • If the group is an issue, which has its own Start Date and Duration values, they are ignored.

Issue Group in the Gantt chart

In order to display child/parent relationships as a group, you first need to enable grouping in Gantt configuration.


Dependencies are displayed as arrows between task bars.

  • Click the arrow to show the Dependency Properties
  • To show/hide dependency arrows, use the Options menu in the toolbar


For more information about managing dependencies, see Dependencies Configuration.

Critical Path

The critical path highlights items that directly affect the project's end date. It includes the task with the latest Finish Date, as well as any items that, if delayed, will also delay that last task - and extend the project's end date.

If a task is part of the critical path, it will have a red task bar.

Critical Path

To switch off Critical Path highlighting:

  1. Select the Options menu in the toolbar
  2. Uncheck Critical Path

The critical path does not affect your chart or the issues within it in any way - it's simply a visual indicator.

Display Options

The Options menu in the Gantt toolbar allows you to select what elements should be shown in the chart.

Status Bar

If there are any inconsistencies in the source data (for example, a cycle of dependencies), the Gantt Info link will be shown on the right side of the Structure status bar (next to the Structure Info link  at the bottom of the screen). Click the link to see details of the inconsistencies.

Gantt Info in the Status Bar

If you do not have permission to edit the Gantt chart, that information will be displayed in the Status Bar as well.
