## Group the Gantt

***

Gantt Views can be grouped by different properties within your plan to organise your Tasks in different ways.

<figure><img src="https://2273109354-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FLu0mYklsCTm7XQm3ZGqv%2Fuploads%2FwKP5qnEiBNM6hQd3xfH4%2FGantt%20Group%20By.svg?alt=media&#x26;token=42c8b418-e29d-4b52-ac12-d622e457b906" alt=""><figcaption></figcaption></figure>

**To change how the Gantt is Grouped:**

* Click the <img src="https://2273109354-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FLu0mYklsCTm7XQm3ZGqv%2Fuploads%2F3oofYkeyY0B6LQb6YzOb%2FSub%20Nav%20Buttons%20(1).svg?alt=media&#x26;token=b752f56a-c695-45a9-a45d-c0f6f35d8ec4" alt="" data-size="line"> 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 <img src="https://2273109354-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FLu0mYklsCTm7XQm3ZGqv%2Fuploads%2FrvTcctNRDtoOHaw7U9zU%2FTheme%3DLight%2C%20Size%3DRegular%2C%20State%3DOn.svg?alt=media&#x26;token=d08029bc-cd20-4401-bc69-8ded58cdca38" alt="" data-size="line">, 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 <img src="https://2273109354-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FLu0mYklsCTm7XQm3ZGqv%2Fuploads%2FCdieZfJMtzDyoueqQ61j%2FView%20Sub%20Nav%20Buttons%20(7).svg?alt=media&#x26;token=2ba30c6b-c36b-4cf5-b9fd-bbe795202092" alt="" data-size="line"> menu in the top left of the Gantt
* Select either `Collapse All` or `Expand All`

<details>

<summary>Group By Rules</summary>

* 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

## Setting the Date Range

***

Gantt Views are very flexible and allow you to visualise any set of Tasks over time.&#x20;

<summary>Date Range Options</summary>

**Preset**

Preset mode offers quick-select options for the most common project viewing timeframes. Simply click on any option to instantly apply that date range to your timeline. These ranges automatically recalculate based on today's date.

| Date Range       | Range                              |
| ---------------- | ---------------------------------- |
| X Week Lookahead | Today + (Project Lookahead Period) |
| Next 30 Days     | Today + Next 30 Days               |
| Next 3 Months    | Today + Next 12 Weeks              |
| Next 6 Months    | Today + Next 25 Weeks              |
| Next 12 Months   | Today + Next 52 Weeks              |
| All Future Tasks | From Today to Last Task            |
| Project to Date  | From First Task to Today           |
| All Tasks        | From First Task to Last Task       |

**Rolling**&#x20;

Rolling mode creates a dynamic window of time that stays centered around today and automatically shifts forward as time passes. Enter the number of days you want to see before and/or after the current date.

| Input     | Calculated Range                     |
| --------- | ------------------------------------ |
| Forwards  | Today + specified days into future   |
| Backwards | Today - specified days into past     |
| Combined  | Full rolling window centred on today |

**Fixed**&#x20;

Fixed mode gives you complete control to select any specific start and end date. Use the date pickers to choose exactly which timeframe you want to view. Unlike other modes, this range stays fixed and doesn't change as days pass.

| Input      | Calculated Range                   |
| ---------- | ---------------------------------- |
| Start Date | Selected start date                |
| End Date   | Selected end date                  |
| Combined   | Fixed range from start to end date |

**Show Surrounding Weeks**&#x20;

This toggle is available in all three modes and provides quick additional context around your selected range. When enabled, it adds one week of visibility before your start date and one week after your end date, making it easier to see what's coming up next or what just happened without changing your core date selection.

| Setting       | Effect on All Mod                                                     |
| ------------- | --------------------------------------------------------------------- |
| Off (default) | Displays exactly the calculated range, no additions                   |
| On            | Adds 1 week before start date + 1 week after end date to visible area |

## 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.

<figure><img src="https://2273109354-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FLu0mYklsCTm7XQm3ZGqv%2Fuploads%2FoDQT1n2yKfAhZDWz7N3j%2FGroup%20143724521.svg?alt=media&#x26;token=c33f3e56-0807-4aa7-8fad-2060bea6883a" alt=""><figcaption></figcaption></figure>

## Gantt Empty States & Hidden Items&#x20;

***

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.

<figure><img src="https://2273109354-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FLu0mYklsCTm7XQm3ZGqv%2Fuploads%2FCtK12dcjG4RhNz7cKBeg%2FEmpty%20Items.png?alt=media&#x26;token=7bb39e0e-8d45-4483-a4e9-b440729c3cb3" alt=""><figcaption></figcaption></figure>

**Empty Gantt Message:**

When no tasks or groups are visible, a message will appear in the Gantt:

**Hidden Items in Folders:**

Look for the ![](https://2273109354-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FLu0mYklsCTm7XQm3ZGqv%2Fuploads%2FXWO95vici7Q574HE956J%2FText%20Buttons%20from%20CX%20Everything.svg?alt=media\&token=e1d05a01-6172-43ec-b574-a5ebf84a4e99) 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.&#x20;

To temporarily reveal the hidden folers:&#x20;

* Click the ![](https://2273109354-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FLu0mYklsCTm7XQm3ZGqv%2Fuploads%2FXWO95vici7Q574HE956J%2FText%20Buttons%20from%20CX%20Everything.svg?alt=media\&token=e1d05a01-6172-43ec-b574-a5ebf84a4e99) 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.&#x20;

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 <img src="https://2273109354-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FLu0mYklsCTm7XQm3ZGqv%2Fuploads%2FNraBjIc2TQadfyAe7Omn%2FTidy%20Up.svg?alt=media&#x26;token=66fc8e15-d00b-44e7-a2cf-6c2f12e7beb7" alt="" data-size="line"> in the bottom left corner.

Refreshing your Aphex window will also trigger the sort order to be re-applied to your Gantt View.

<details>

<summary>Sort Order Logic</summary>

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

</details>

* Use the <img src="https://2273109354-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FLu0mYklsCTm7XQm3ZGqv%2Fuploads%2Fr7WCpGhKtUJn8O1253fS%2FGantt%20Zoom.svg?alt=media&#x26;token=5327b0a3-d3f7-4677-9adf-3b8d2ee6830d" alt="" data-size="line"> 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.&#x20;

## Group Dates & Durations

***

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.

## Task Bar Colours & Icons

***

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.
