# Visualization and Display Questions

> Common questions about visual display, baselines, export, columns, and appearance customization in Nextedy GANTT.

<Info title="Verify in application">
  This page covers visualization features at a high level. Refer to the [Reference](/gantt/reference/index) section for detailed property documentation.

<AccordionGroup>
  <Accordion title="How do I compare the current schedule against a baseline?">
    Gantt supports baselines for comparing your current schedule against a saved snapshot. The Compare with History feature allows you to select a historical date, a named baseline, or a specific revision number. When active, baseline bars appear below the actual task bars, showing the originally planned start and end dates alongside the current dates.
  </Accordion>

  <Accordion title="Can I export the Gantt chart as an image?">
    Yes, Gantt provides an export-to-PNG feature accessible from the toolbar. The export panel renders the Gantt chart as an image and provides download and print buttons. You can apply date filtering to control which portion of the schedule is included in the export.

    <Note title="PDF export not supported">
      The Gantt widget cannot be exported to PDF format. Use the PNG export feature for sharing static schedule snapshots.
    </Note>
  </Accordion>

  <Accordion title="How do I customize task bar colors?">
    Task bar colors can be set in two ways. Each work item type has a default color that is automatically applied to its task bars. For more dynamic control, use item scripts to apply conditional color logic based on work item fields such as status, priority, or custom attributes. See [Scripting Questions](/gantt/faq/scripting) for more on item scripts.

    | Method                       | Scope                      | Configuration                                 |
    | ---------------------------- | -------------------------- | --------------------------------------------- |
    | Work item type default color | All tasks of a type        | Polarion work item type settings              |
    | Item script color logic      | Per task, conditional      | Custom item script with color return value    |
    | `color` / `taskColor` field  | Per task, from field value | Map a custom field to the task color property |
  </Accordion>

  <Accordion title="What columns can I display in the Gantt grid?">
    The Gantt grid supports configurable columns with multiple template types including start date, end date, deadline, owner/assignees, duration, progress, and custom columns. The assignee column supports two display modes: `initials` (showing user initials in circles) and `fullname` (showing full names). A special workload column appears when you select a resource in the resource view.
  </Accordion>

  <Accordion title="How do I access the column and display settings menu?">
    Click the hamburger menu icon in the first column header of the Gantt grid. This opens a menu with options for column visibility, timescale selection, and navigation settings. You can show or hide columns and adjust the timescale granularity from this menu.
  </Accordion>

  <Accordion title="Can I hide the Gantt toolbar?">
    Yes, set the `hideToolbar` widget parameter to `true` to hide the entire toolbar. When the toolbar is hidden and you are in edit mode, a floating save button appears as a fallback so you can still save your changes.

    <Info title="Verify in application">
      When using `hideToolbar`, ensure users have an alternative way to access essential functions like save and refresh.
    </Info>
  </Accordion>

  <Accordion title="How do I show only leaf tasks without parent summary rows?">
    Set the `onlyLeafTasks` widget parameter to `true` to display only leaf-level tasks (tasks with no children). Parent summary tasks are hidden from the Gantt chart, giving you a flat view of all actionable work items without the hierarchical grouping.
  </Accordion>

  <Accordion title="What visual indicators show task status?">
    The Gantt chart uses several visual indicators to communicate task status at a glance:

    * **Progress fill** -- the filled portion of each task bar shows completion percentage
    * **Overdue deadlines** -- deadline column values turn red when the task is past due
    * **Risk indicator** -- tasks at risk (past end date) are highlighted with a warning color
    * **Conflict markers** -- tasks with parent-child date range conflicts display a visual conflict indicator
    * **Unplanned indicator** -- tasks with no scheduled dates appear with a special unplanned marker

    For additional display customization, explore the [Guides](/gantt/guides/index) section.
