Gantt charts can be viewed by all user types (including collaborators) on all paid accounts.
Use the Gantt chart to see how tasks in your folder, project, or space are scheduled and to quickly make adjustments to your project's timeline.
The timeline on the chart's right side shows scheduled tasks as bars, which extend from the task's start to end dates. The table on the left side of the view shows all tasks, including tasks that haven’t been scheduled.
To view a folder, project, or space on the Gantt chart:
Navigate to a folder, project, or space.
Switch to Gantt Chart.
By default, tasks appear in the color associated with their status on the timeline portion of the chart.
You can check the Highlight overdue box to have all overdue tasks color-coded red.
You can change what you see on the timeline. Click the three-dot menu button next to Snapshots and select to show (or hide):
Click the icon on the panel above the timeline to open the Gantt chart in full-screen mode.
A folder, project, or space name appears on the timeline and a bracket appears under the name. A project bracket color depends on the project status.
The bracket will always span from the earliest start date to the end date of the latest task within the project, even if the project has its own start and end dates that were set in the info panel. Start and end dates from those fields aren't displayed on the Gantt chart.
To see the actual dates on the Gantt chart, for which the project is scheduled, you can enable the Dates Rollup feature from Wrike Labs. This way, the bracket will be displayed with the project’s own dates as a bold filling, while the part representing dates of tasks that fall outside this timeframe will have no filling on the timeline, just an outline.
A project or folder icon appears to the left of a folder's or project’s title. A folder icon is shown next to the space name.
The table portion of the Gantt chart gives you easier access to all items from the selected folder, project, or space. You can add and delete columns there as you would do in Table view.
You can expand and collapse a folder, project, or space's content using the caret icon to the left of the folder, project, or space's name. If you want to see all the content expanded (including all subfolders) hold Ctrl (Cmd if you're on Mac) and click the caret icon. Use the same combination to collapse all items at once.
Hide (or show) the table portion:
Hover over the right border of the table (or left side of the view if the table is hidden).
Click the blue button with the caret icon.
When you hide the table you can expand and collapse folders and projects on the timeline using the + and - buttons, which appear to the left of the timeline. Each + or - is at the same level as the title of the parent task, folder, or project it corresponds to.
Add (or delete) columns to the table:
Click the gear icon in the table’s upper left-hand corner.
Check the box next to any columns you want to see or uncheck the box next to any columns you want to hide. The table has a fixed width and in case there are too many columns selected, you can scroll to the needed column from the bottom of the table.
Hide folders that don't have any tasks in them from the view (both the table and timeline portions).
Hide empty folders: Click the Hide empty folders icon (located at the top of the view). The icon turns blue.
View empty folders: Click the Hide empty folders icon again. The icon turns back to black.
This setting only affects folders. Empty projects will stay in place even if you choose to hide empty folders. Use project filters to hide or show folders on the Gantt chart.
