ProScheduler provides both Timeline and Gantt chart features.

Timeline and Gantt chart share a similar view of tasks list and the calendar, however they are different in some points

• Task hierarchy in Timeline is the Issue hierarchy in Jira (Epic → Issue → Sub-task) while Gantt chart maintains a custom hierarchy based on the Work Breakdown Structure (WBS) number

• Gantt chart provides advanced Gantt features such as baseline, critical path, inline task creation, drag&drop to update task hierarchy. Timeline doesn’t have those features.

You can choose to use one of them or both in the Feature settings
