In other words, a task that is 60% complete would be 60% shaded, starting from the left . A vertical line is drawn at the time index when the progress Gantt chart is created, and this line can then be compared with shaded tasks . If everything is on schedule, all task portions left of the line will be shaded, and all task portions right of the line will not be shaded . This provides a visual representation of how the project and its tasks are ahead or behind schedule . </P>
