The Gantt chart gives you a time-based view of your projects and tasks; What tasks are planned and when are they to be executed. In the Gantt chart, you can also see dependencies between tasks and who is assigned to a task.

A Gantt chart allows you to see at a glance:

  • Project start and end dates

  • Task start and end dates

  • What the task is

  • Who is assigned to the task

  • If tasks overlap

  • Dependencies between tasks


General data is required for all portlets.

General configuration

Advanced settings

  • Start of period: number of historical days to be rendered

  • End of period: number of days ahead to be rendered

  • Collapse all tasks: setting if the Gantt should open with all tasks collapsed

  • Enable virtual scrolling: virtual scroll can be disabled or enabled. Row virtualization allows you to load and render many tasks in Gantt with effective performance. In this mode, all tasks are fetched initially from the data source and rendered in the DOM within a compact viewport area.

  • Use ISO week format: Check if the ISO week number should be shown in the Gantt (available on two zoom levels). If this setting is not checked the date of the first day of the period will be shown.

  • Start day of the week: Set the start day of the week; 0 = Sunday, 1 = Monday etc. If Use ISO week format is checked, the start day of the week will be set to 1.
