A further feature of the Gantt chart is the Date Line.

IIn addition to the options of Holidays and Date Line empower® charts allows you to add highlights to your calendar, e.g. for a specific time period of a project or vacation.
Below the highlight is a text box which provides the same editing options as that of the Date Line. In addition, you can move or extend the highlight manually to any date. To do so, move your cursor below the highlighted section in order to display the context menu that allows you to do so.
Sometimes a project encounters delays. empower® charts allows you to add delays to your project calendar. Click Add… in the Action Bar and select Delay to add a delay to your calendar. An entry field will appear in which you can specify the begin and end of a period, alternatively you can enter these date via the calendar view. Confirm the changes by clicking OK.
The delay in your project plan will be automatically inserted into your Gantt chart. A click on the enlargement arrow allows you to hide or display the hatched area as well as any labelling. Here, you also have the ability to change the color as well as completely remove the enlargement from the Gantt chart.
