For a project/task to be displayed as a bar in a Gantt chart, it must have an Estimated Start Date and an Estimated End Date. If a project/task has both an Estimated Start Date and an Estimated End Date, but you still cannot see a bar in the Gantt chart for it, it may be that its time frame is outside the timeline currently displayed in the Gantt chart. You may move back and forth in the timeline using the navigation tools.
