Here is how you can activate and use progress lines to monitor the progress of your site.
Progress lines display visually how your site is doing. The line can be seen in the Gantt mode as a red line going through the schedule. Currently there are two types of progress lines: most late line and progress percentage line. The progress lines are calculated based on the statuses of your work packages and when they are scheduled to be done.
The most late option shows you where the most late work package is inside a work phase. The Progress percentage line shows the percentage.
