There is a report called the Periscope report that is a Gantt chart alternative. It produces a similar visual chart:
Projects, milestones and tasks can be viewed in the report, giving project managers a detailed timeline. The Periscope report is useful for scheduling new projects and getting a clearer picture of progress on current projects. In addition, the report can be filtered by individual team members to see how they are progressing on their tasks for a particular project or milestone.
