Project - Tasks tab - Gantt chart

Updated in 2025

The Gantt chart is a graphical representation of project tasks across a timeline. You can use the chart to schedule tasks and assess the progress of the overall project.

Overview

On the left side of the Gantt chart, all tasks are arranged in a grid with the following columns:

• Name: The name of the task. The task name aggregates the ID and the summary of the Task. For details, see General tab.

• Assignee: The name of the person assigned to complete the task.

• Start: The planned start date of the task. This field also displays whether the task is on time, late or ahead by comparing planned start time against real start time.

• Finish: The planned end date of the task. This field also displays whether the Task is on time, late or ahead by comparing planned end time against real end time.

All tasks are organized in the hierarchical tree, revealing the breakdown structure of the work to be done on a project. Using the grid, you can create new tasks, manage tasks hierarchy, customize tasks and perform other workflow actions available.

On the right side of the Gantt chart, you can see the illustration of your project tasks in colored bars. The bars show the duration of your tasks against the progression of time. For each task, the associated bar begins at the start date and ends at the finish date. The Gantt chart also shows special tasks, called milestones. A milestone is used to indicate any critical point of the project. All milestones are shown with the diamond icons . With the task bar, you can schedule tasks and monitor their progression states.

Color coding

The color of the bar is based on the task state and the percent complete.

Color	Explanation
Light green bar	The task is pending or open and has 0% completion.
Bright green bar	The task is in progress or completed, with 1–100% completion. The bright green portion indicates how much of the task is complete.
Light red bar	The task is unscheduled (missing planned dates).
Bright red bar	The task is unscheduled but has 1–100% completion. The bright red portion indicates the percentage completed. The task may be in the In Progress or Completed state.

TIP: If a task bar appears in red, it may indicate scheduling inconsistencies. Review the task’s dates and the overall project schedule to resolve potential issues.
