The Gantt chart is the primary scheduling view in Kirra Scheduler. It displays all blasts across four collapsible sections: PATTERN PREP, DRILLING, LOADING, and BLASTING.

The chart is divided into a fixed left panel and a scrollable timeline on the right.
| Column | Description |

| Blast | Blast name with an inline pencil edit icon. For split blasts, block sub-rows show a [A] / [B] label prefix. |

| Section | Info Displayed |
|---|---|
| PATTERN PREP | Assigned ancillary equipment IDs, prep duration (days) |
| DRILLING | Assigned drill IDs, total meters, dependency/maintenance warning icons |
| LOADING | Assigned MPU IDs, explosive mass (kg), dependency warning icons |
| BLASTING | Volume (bcm) |
One column per calendar day. Weekend columns are dimmed for easy identification.
| Bar | Section | Colour | Description |

Click and drag any bar to shift its dates:
Drag the left or right edge of any bar to adjust its start date or duration:
Click any section header (PATTERN PREP, DRILLING, LOADING, BLASTING) to collapse or expand its rows. The collapse state persists within the session. This is useful when you only need to focus on one phase at a time.
Hold Shift + Scroll or Alt + Scroll to scroll the Gantt timeline left and right.
Hold Ctrl (or Cmd on Mac) and click multiple blast names to select them. Multi-selected blasts can be acted on together via the context menu.
Drag a blast name vertically to reorder it within the schedule. The new order persists across re-renders.
Right-click any blast name to access:
A sidebar palette appears beside the Gantt chart for drag-and-drop assignment:
Click Auto Schedule in the toolbar to automatically stack and sequence blasts. The auto-scheduler orders blasts by drill start, stacks drilling across available rigs, and applies the Drill Overlap % setting to control overlap between consecutive blasts.
Click Recalc Dates to run the dependency engine across all blasts, updating loading start dates and blast dates.
The settings bar includes planning period controls for visual banding on the timeline:
| Control | Description |
|---|---|
| Week Start Day | Choose which day of the week the Gantt columns align to (Monday, Tuesday, etc.). This affects the weekend shading and week number labels. |
| Plan Cycle (Weeks) | Set how many weeks make up a repeating planning cycle (e.g., 2, 4, 6). The timeline alternates background colours for each cycle period, helping you distinguish planning periods visually. |
| Per-Week Colours | Click the colour palette button to open a popup where you can assign custom colours to each week within a cycle. This is useful for colour-coding fortnightly or monthly planning periods. |

A delay palette appears in the sidebar for drag-and-drop delay assignment:
| Delay Type | Description |
|---|---|
| UD | Unplanned Downtime |
| SD | Scheduled Downtime |
| SM | Scheduled Maintenance |
| Weather | Weather delay |
| Custom | User-defined delay types |
Drag a delay chip onto a drill, load, or prep bar to add a schedule interruption. The delay appears as a hatched or coloured overlay on the Gantt bar. Right-click a delay to extend, shrink, or remove it.
