Step 1: Open the Gantt Chart

Navigate to the Polarion page containing your Gantt widget with the resource view enabled. If you have not yet enabled the resource view, set Show Resource View to Yes in the widget parameters.

​
Step 2: Toggle Resource Hiding from the Toolbar

Click the Hide Empty Resources button in the Gantt toolbar. This toggles the visibility of resource rows that have no tasks in the currently visible time range and filter scope. When activated:
  • Resources with zero visible tasks are hidden from the resource view
  • Resources with at least one visible task remain displayed
  • The toggle state is preserved while you interact with the chart
The hide empty resources toggle is available in the Gantt toolbar alongside other view controls. Look for it in the resource view section of the toolbar buttons.

​
How Resource Hiding Works

The resource hiding behavior evaluates each resource against the current view state:
ConditionResource Visible?
Resource has tasks in current filterYes
Resource has no tasks in current filterHidden
Filter changes to include resource tasksAutomatically shown
Filter changes to exclude all resource tasksAutomatically hidden
Resource visibility is re-evaluated automatically when:
  • You apply or change a filter
  • Tasks are added or removed
  • The visible time range changes
Resource hiding and the Show Unassigned option serve different purposes. Show Unassigned controls whether work items without an assignee appear in a dedicated “Unassigned” row. Hide Empty Resources controls whether resource rows with no assigned tasks are shown. These are independent features that can be used together.

​
Step 3: Combine with Resource Filtering (Optional)

You can combine resource hiding with resource-specific filtering for targeted views:
  1. Enable resource hiding via the toolbar toggle
  2. Use the resource filter to narrow down to specific resources
  3. When a resource filter is active, only the filtered resource is shown — all other resources are hidden regardless of task assignments
Items that are filtered from the task row list may still appear in the resource view markers. Only items that are explicitly hidden are excluded from marker calculations. This is by design to ensure resource load calculations remain accurate even when the task list is filtered.

​
Step 4: Verify Resource Hiding

After enabling the toggle:
  1. Check that resources with no tasks in the current view are no longer displayed
  2. Apply a filter that excludes some tasks — verify that resources losing all visible tasks disappear
  3. Remove the filter — verify that previously hidden resources reappear
Resource hiding is especially useful for charts with many team members. It keeps the resource view focused on active contributors for the current time period, making overallocation detection faster and clearer.

​
Verification

You should now see:
  • Only resources with active tasks displayed in the resource view
  • Resource rows automatically appearing and disappearing as you change filters or the visible time range
  • The hide empty resources toggle in the toolbar controlling the behavior
