Gantt

Who can use this feature?

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.

  • Click the menu in the top left of the Gantt

  • Select either Collapse All or Expand All


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

  • Choose your preferred mode from the selector:


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

  • Click to create an additional filter group

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.


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.


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 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.

  • Click at the top of the Gantt

  • Select from Resource, Baseline, Critical Path

  • To compare the Live Plan to a previous week, select 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.

  • Click

  • Select Group Duration Calendar

  • Choose one out of: Project Default, 5 Day Week, 7 Day Week

  • 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

  • Click the button at the top of the Gantt

  • Set the toggles to or to hide or reveal any combination of columns

  • Once a column is enabled, select any cell to change the value


Every colour and icon on the Gantt tells you something. Whether it’s a Milestone, a delay, or who is responsible for the work - you can choose what shows and how it looks.

  • Click in the top right of the Gantt

  • Select Bar Colour

  • Choose how you’d like to colour the Gantt; by Subcontractor, Shift, or Owner

  • Hover over the icon to see:

    • The Filtered value

    To Collapse and Expand Groups:

    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 Flattened Mode, which condenses the Folder path into a single row to save vertical space on the Gantt

    Show Surrounding Weeks

    This toggle is available in all three modes and provides quick additional context around your selected range.
