Working with Gantt Charts

The following guide will help you get started working with your Gantt charts. For additional information on the topics discussed, see our Structure.Gantt User's Guide.

Scheduling Tasks

Tasks can be scheduled automatically by Structure.Gantt or manually.

Automatic Scheduling 

In this mode, tasks are automatically placed on the Gantt timeline based on your project start date, task estimates, predecessors and dependency types.

Manually Scheduled Tasks

Manual Scheduling

Manual scheduling allows you to schedule items based on an the values in a Jira field and/or by dragging tasks across the timeline.

Manually scheduled Gantt chart

As you set the Start/Finish Date of a task, the task is considered to be scheduled manually. This means it will stay at the defined position regardless of its dependencies. If you remove the Start/Finish Date for a task, it will become automatically scheduled again.

For more information, see Automatic Scheduling.

Adjusting Task Duration

The duration of tasks within the Gantt chart are calculated based on each task's work estimate, the Work Estimates Configuration and the calendar.

To adjust a task's duration:

  1. Edit the task's work estimate fields, or
  2. Drag the side of the task bar.

Drag the right side of a task to update it's duration

For more information, see Adjusting Task Duration.

Managing Dependencies

Dependencies are defined based on Issue Links. Changing dependencies creates or removes links between issues.

Finish to Start Dependency

To create a Finish to Start dependency:

  1. Mouse over the task bar until a black circle appears to the right of the bar
  2. Press the circle and drag your dependency line to the task you want to link to

To create other types of dependencies, use the Link button in the toolbar.

To remove a dependency:

  1. Click the link arrow between two tasks to display the Dependency Properties
  2. Click Remove

For more information about working with and configuring dependencies, see Dependencies.

Scheduling Conflicts

Structure.Gantt highlights any scheduling conflicts with a red line (see picture). For example, for finish to start dependencies, if a task is manually scheduled for a date earlier than its predecessor's Finish Date, Gantt will highlight this conflict.

Scheduling Conflict

To deal with the conflict, click the task and select one of the following actions:

  • Respect Link. This will change the task Start Date to coincide with the predecessor's Finish Date. The task will stay in the Manual Scheduling mode.
  • Auto Schedule. This will switch the task to the Automatic Scheduling mode, clearing its Start Date or Finish Date and scheduling the task based on its predecessor and the dependency type.

Next Steps

Congratulations! You're ready to build your first Gantt chart!
