A Gantt chart graphically presents project scheduling information by displaying the duration of tasks. One axis contains the time series, and the other contains tasks. You can use color-coded bars to show the planned duration of the stages to complete the tasks. Bars can use multiple colors to differentiate between stages. Gantt charts use symbols on bars to mark beginning and ending dates. The colors of the bars represent the task status. Optionally, markers designate the start and end dates of tasks. Figure 8‑12 shows a Gantt chart.
