What is a Gantt chart?
Gantt charts are a project planning tool used to represent the timing of tasks required to complete a project. Because Gantt charts are simple to understand, they are used by most project managers to illustrate completion or progress.

In a Gantt chart, each task takes up one row. Dates run along the top. The expected time for each task is represented by a horizontal bar: the left end represents the beginning of the tasks, while the right end show its expected date of completion. As the project progresses and tasks become partially done or completed, the color of the horizontal bars will change to reflect completion or percentage of completion.

How can I see all my tasks in this chart, without having to browse numerous pages?
The number of tasks displayed on each page of the Gantt chart can be set under "My Office -> My Preferences". To see all tasks on one page in the Gantt chart, click the "My Office" tab, then click on "My Preferences" on the left panel. In "My Preferences", you can select to display up to 100 tasks per page. Simply click on the "Update" button to enable your changes and return to your Gantt chart.

Why is my progress bar only grey? Why is my progress bar only red?
The progress bar will change from grey to red as the task becomes partially or totally completed. A task that is not started will be marked as 0% done. Its progress bar will be completely grey. A task that is completed will be marked as 100% done, or that has its status as completed, its progress bar will be completely red. Other tasks will be partly grey and partly red, proportional to the percentage of completion.

Some tasks have no progress bar. Why?
There are 2 important requirements for a task to have a progress bar in the Gantt chart: it must have a start date AND an end date. If your task only has a start date or only has an end date, it will not have a progress bar.

If your task has both a start and an end date, but you still cannot see its progress bar in the Gantt chart, it may be that its time frame is set in another month. Simply click on the arrows next to the month to move back or forward in time.
