Project Users with Full Planner Access can create and open Gantt Views.
Group the Gantt
Gantt Views can be grouped by different properties within your plan to organise your Tasks in different ways.
To change how the Gantt is Grouped:
Click the menu in the top left of the Gantt
Select a Primary Grouping. Pick from Folder, Owner, Package, Shift or Location
Optionally, select a Sub-Grouping to apply another level of structure beneath the Primary Group
When Hide Empty Primary Groups is , only Groups that contain visible Tasks will show on the Gantt. Any Groups without Tasks in your current View will be hidden.
To Collapse and Expand Groups:
Click the menu in the top left of the Gantt
Select either Collapse All or Expand All
Group By Rules
Choose a Primary and Sub Grouping to shape how your Gantt is displayed
e.g. Group by Subcontractor, then by Shift, to see separate swimlanes for each combo
The layout updates instantly as you change grouping options
All Primary groupings, except Folders, can be rearranged into a custom order, per user
Sub Groupings only show groups that contain tasks - empty groups won’t appear
Folder Grouping can be switched between a nested Tree Mode and a FlattenedMode, which condenses the Folder path into a single row to save vertical space on the Gantt
Setting the Date Range
Gantt Views are very flexible and allow you to visualise any set of Tasks over time.
To change the visible Date Range on the Gantt:
Click at the top of the Gantt
Yours might also look similar to or

Filtering the Gantt
Filters in Aphex let you show only what matters, whether that’s Tasks with certain properties, or ones that are missing something. Keep it simple or build something more detailed, it's up to you.
To filter the Tasks you see in a Gantt View:
Click at the top of the Gantt
In the dropdown that appears select and choose the property you'd like to filter by
Change the logic from options like or to or to hide or reveal the relevant Tasks
Click to swap between and
Using Filter Groups:
Groups are helpful when combining logic and logic in your filter
Archived values that are still in use will appear as filter options. Unused archived values will be hidden from the filter options
Tasks that do not match the filter criteria will be hidden from the Gantt
Gantt Empty States & Hidden Items
If your Gantt looks empty, it's usually because settings like Filters, your Date Range, or the Hide Empty Groups toggle are hiding your tasks or groups. Aphex provides clear messages and icons to help you adjust your view.
Empty Gantt Message:
When no tasks or groups are visible, a message will appear in the Gantt:
Looks like your Gantt is empty
Try adjusting or to reveal activities and groups
To reveal your tasks, simply click the highlighted or in the message to open the relevant panel and adjust your view settings.
Hidden Groups Notification:
When the Hide Empty Groups toggle is active, a notification appears at the top of the Gantt if any groups (Folder, Location, Owner, Package, Shift or Subcontractor) are hidden as a result:
[X] Hidden [Group Type]
Adjust your and configuration to reveal hidden groups
To reveal hidden groups:
Click the highlighted or in the message to open the relevant panel and adjust your view settings.
Open [View Settings Icon] and set the Hide Empty Groups toggle to [Toggle Off Icon].
Hidden Items in Folders:
Look for the next to a Folder Row. This icon indicates the folder contains subfolders, but they are hidden by your current Filters, Date Range, or Hide Empty Toggle.
To temporarily reveal the hidden folers:
Click the next to the folder name. This displays the contents without changing your overall Gantt view.
Task Sort Order
Tasks on the Gantt will always be sorted by Start Date - the earlier a Task starts, the higher it will appear within it's grouping.
Aphex will hold the position of your Tasks while you make edits, and then when you're ready to re-apply the Sort Order, click in the bottom left corner.
Refreshing your Aphex window will also trigger the sort order to be re-applied to your Gantt View.
Sort Order Logic
The Gantt Sort Order is fixed, and will always follow this logic:
First it will sort tasks by Start Date
If the Start Date is the same, it will then check End Date
If the End Date is the same, it will then apply Alphanumeric sorting
Gantt Zoom
You can view your projects on a range of time scales, from a single day to a full year:
Head to the bottom-right corner of your Gantt
Use the menu to switch between Day, Week, Month, or Year
The Gantt will instantly update to show your plan on the scale you’ve selected
Overlays
Overlays let you layer in things like baselines, critical path visibility, or daily resource demand. This means you can add extra context to your Gantt without changing up or leaving your View.
To turn Overlays on and off:
Click at the top off the Gantt
Select from Resource, Baseline, Critical Path
To compare the Live Plan to a previous week, select Baseline
This will show a list of all Published Versions, and all Master Schedule Imports
Select any option to see how how your current plan compares to your baseline
When viewing your Gantt, Aphex automatically calculates a Start Date, End Date, and Duration for Folders, Packages, and Parent Tasks. These adjust based on what’s visible in your View and which working calendar you chose to apply.
To change your Group Duration Calendar:
Click
Select Group Duration Calendar
Choose one out of: Project Default, 5 Day Week, 7 Day Week
To view Group Durations & Dates on the Gantt:
Open the Column Picker and toggle Duration or Start / End
These values change dynamically with Filters or Date Range updates
Filtered values are marked with a icon so you know they’ve been adjusted
Respects the non-working days of your Project's Default Calendar
5 Day Week
(Mon–Fri) Static calendar
7 Day Week
(Mon–Sun) Static calendar
This setting only affects how Durations are displayed for Folders, Packages, and Parent Tasks. It doesn’t change individual Task calendars or impact other users.
When a plan is published, Group Durations are always calculated using a 5 day workweek (Monday–Friday).
