- Detailed tasks are displayed with a light blue Gantt bar with the names of the assigned resources shown at the right end of the Gantt bar.
- Milestone tasks are displayed as a black diamond with theFinishdate of the task shown to the right of the milestone symbol.

The default formatting of Gantt chart pane looks like as below:

Formatting Gantt Chart Pane
Microsoft Project offers you many ways to apply custom formatting to theGantt Chartpane portion of theGantt Chartview. For example, suppose that we want to format theGantt Chartpane with the following requirements:
- Display summary tasks as a green square bracket with the% Completevalue shown to the right of the summary task symbol.
- Display detailed tasks with a light green color, with the initials of the assigned resources shownabovethe Gantt bar, and the% Completevalue shown to the right of the Gantt bar.
- Display milestone symbols as a red diamond, with theFinishdate shown to theleftof the milestone symbol, and the% Completevalue shown to the right of the milestone symbol.
- Display link lines using a curved arrow rather than the “right angle” arrow.

Bar Styles in Gantt Chart
To make the above formatting changes, we will need to take advantage of the power of theBar Stylesdialog. The fastest way to access Bar Styles dialog is to double click anywhere in the white part of the Gantt Chart pane. You can also access the Bar Styles dialog from Gantt Chart Formating ribbon. Clicking Format pick list button in the bar styles sections of ribbon will show you the Bar Styles option. Using either method, Microsoft Projects displays default Bar Style dialog shown in the figure.

TheBar Stylesdialog displays a data grid that includes every symbol currently available in the applied view. For example, notice that the list includes items such as theTask,Split,Milestone, andSummarysymbols. To the right of each symbol, the data grid includes columns with the instructions for how Microsoft Project will draw the symbol. For example, notice that theTasksymbol is drawn from theTask Startdate to theTask Finishdate, as shown in theFromandTocolumns for theTaskitem in the data grid.
At the bottom of the data grid, theBar Stylesdialog includes two additional formatting sections, and each section is displayed with its own worksheet tab. When you click theBarstab, theBarssection includes the formatting instructions for the start, middle, and end portions of the symbol, including the color used for each portion. When you click theTexttab, theTextsection shows what text to display at the left and right ends of the symbol, as well as on the top, bottom, and inside of the symbol.

Summary
A Gantt chart is a visual tool that helps in scheduling and decision-making processes by depicting tasks, milestones, and their corresponding start and end dates. We can modify the Gantt Charts in Microsoft Projects to make them more appealing and informative for the target audience. By carefully modifying the Gantt Chart views, we can grab attention of the stakeholders on important tasks that need more discussion and corrective actions.
