Using the Gantt chart interface?

The Gantt chart contains bars on a timeline that graphically represent your tasks.

In most cases, you can click and drag a bar to change its start and end dates. You can also drag either end of the bar to resize it, making its duration longer or shorter. If you attempt to resize or move a bar, but the bar "snaps back" to its original position, it is likely due to a constraint or dependency that is placed on the task. For more information, see Gantt constraints and dependencies.

The task bars in the Gantt chart are color-coded based on several conditions, such as percent completion, whether the task is part of the critical path, and whether the task is an umbrella task. Most of the conditions and corresponding bar colors are noted in the legend.

The Gantt chart can be viewed in various time frames by using the Zoom dropdown on the Gantt scheduler toolbar. You can zoom to Months, Weeks, Days, and Hours. You can also click the Zoom in Zoom in and Zoom out Zoom out buttons on the toolbar to step through the Month, Week, Day, and Hour views. The Zoom to fit page Zoom to fit page button widens the chart. To focus on a specific task right-click the bar on the chart and select Zoom to the bar.

The space that the Gantt chart occupies depends on several factors, which include whether the project window is maximized, the last zoom option selected, and the number of visible columns in the task table. On the chart, you can right-click an empty space and select Zoom to fit to actual space to widen the chart. You can also widen the chart by moving the vertical divider between the chart and the task table. You can also hide columns in the task table by clicking the Choose columns to display Choose columns to display button on the Gantt scheduler toolbar.

Note: If you create more tasks in the Gantt scheduler, make sure to not hide required columns that contain fields that are needed to create new tasks. If you see a Missing required field message when you try to save a new task, one of the required columns might be hidden: Task Name, Planned Start, or Type. In this case, the column reappears and the field where the information is needed is highlighted in a different color from the rest of the fields.
