Gantt¶
The Gantt chart provides a day-by-day (week or month) view of your planned schedules.
It allows you to view, move, and resize production and non-production schedules. This section is the complete reference for how schedules behave when you interact with them.
Colour Legend¶
A legend is displayed above the chart showing what each colour means:
| Category | Status | Colour |
|---|---|---|
| Production | Running | Green |
| Production | Completed | Light green |
| Production | Planned | Green (darkened) |
| Non-Production | Running | Blue |
| Non-Production | Completed | Light blue |
| Non-Production | Planned | Blue (darkened) |
Schedule Types¶
How a schedule can be moved or resized depends on its order type. Each production schedule displays its order type as a badge.
| Acronym | Order Type | Description |
|---|---|---|
| FQ | Fixed Quantity | Schedule has a set quantity but no specified end time. The ideal end time is calculated automatically from the cycle time of the SKU. |
| FE | Fixed End | Schedule has a set end time but no specific quantity (i.e., fixed duration). |
| FQE | Fixed Quantity & End | Schedule has both a specific quantity and end time. The normal SKU cycle time will be ignored. |
| C | Continuous | Schedule has neither a set quantity nor end time. The station will remain on this SKU until manually ended. |
Start/End Mode¶
Each production schedule also displays a start/end mode badge indicating how it will be started and stopped. This is only shown for schedules that have not ended.
| Acronym | Mode | Description |
|---|---|---|
| ASE | Auto Start & End | Schedule will automatically start and end at the planned times, regardless of quantity completed. |
| AS | Auto Start | Schedule will automatically start at the planned start time. |
| AE | Auto End | Schedule will automatically end at the planned end time, regardless of quantity completed. |
| M | Manual | Schedule will need to be manually started and ended by the operator. |
Hovering Over a Schedule¶
Gantt Bar Tooltip¶
Hovering over a schedule bar on the Gantt chart shows a tooltip with: work order reference, SKU name, quantity (or ∞ for continuous), order type acronym, and start/end mode acronym.
Schedule Detail Panel¶
When a schedule is selected, hovering over start or end times (shown with a dashed underline) in the detail panel reveals additional timing details:
- Actual Start — when the schedule actually started
- Actual End — when the schedule actually ended
- Ideal End — when the schedule is expected to end based on production speed
Hovering over the order type or start/end mode badges shows their full description.
Moving a Schedule (Drag)¶
You can drag a schedule left or right to change when it starts. All times snap to 15-minute intervals. Schedules cannot be moved between stations. Schedules cannot be moved to a time in the past.
Not Started Schedules¶
| Order Type | What happens when you drag |
|---|---|
| FQ (Fixed Quantity) | The schedule moves to the new start time. The expected duration stays the same. |
| FE (Fixed End) | The schedule moves as a fixed-length block — both start and end shift together. |
| FQE (Fixed Quantity & End) | Same as Fixed End — the block moves together. |
| C (Continuous) | The start time moves. The bar continues to extend to the edge of the visible time range. |
If the schedule has auto-start enabled, the automatic start time is also updated to match the new position.
Running Schedules¶
Running schedules cannot be dragged. Once a schedule has started, its start time is locked.
Completed Schedules¶
Completed schedules cannot be dragged.
Resizing a Schedule¶
You can resize a schedule by dragging its start or end edge to make it longer or shorter. All times snap to 15-minute intervals.
Not Started Schedules¶
| Order Type | Drag start edge | Drag end edge |
|---|---|---|
| FQ (Fixed Quantity) | Not allowed — "Cannot set the end time of a 'Fixed Quantity' type schedule. To move the start time, drag from the centre of the box." | Not allowed (same message) |
| FE (Fixed End) | Changes the start time | Changes the end time |
| FQE (Fixed Quantity & End) | Changes the start time | Changes the end time |
| C (Continuous) | No resize handles | No resize handles |
If the schedule has auto-start or auto-end enabled, the automatic times are also updated to match.
Running Schedules¶
The start edge cannot be resized on a running schedule — a message will appear: "Cannot change the start time of a running schedule."
| Order Type | Drag end edge |
|---|---|
| FQ (Fixed Quantity) | Not allowed — "Cannot set the end time of a 'Fixed Quantity' type schedule. To move the start time, drag from the centre of the box." |
| FE (Fixed End) | Changes the end time |
| FQE (Fixed Quantity & End) | Changes the end time |
| C (Continuous) | No resize handles |
Completed Schedules¶
Completed schedules cannot be resized.
Confirmation Dialog¶
After any drag or resize operation, a confirmation dialog is shown before the change is saved. The dialog displays the before and after values for the start and end times.
If the schedule has auto-start or auto-end enabled, the dialog also notes this:
- "This schedule will start and end automatically when planned." (ASE)
- "This schedule will start automatically when planned." (AS)
- "This schedule will end automatically when planned." (AE)
Editing a Schedule¶
From the Gantt Chart¶
Click on a schedule to open the detail panel, then click Edit to open the edit form.
- Not started schedules — all fields can be edited
- Running schedules — the start time is locked and cannot be changed; all other fields remain editable
- Completed schedules — the Edit button is greyed out and the form cannot be opened
Continuous Schedules¶
Continuous schedules have no defined end time. On the Gantt chart, they are shown as a bar that extends to the right edge of the currently visible time range (whether viewing by day, week, or month). The bar length updates automatically when switching between views.
