Gantt View
Gantt is one of the views in the Scheduling workspace. It provides a timeline-based visualization of your scheduled projects, displaying them as horizontal bars on a timeline. This view is ideal for understanding project sequences, identifying timeline gaps, and planning resource allocation over extended periods.
Quick Start: Use the Gantt View
- Open Scheduling from the sidebar
- Click Gantt in the toolbar view switcher
- View the timeline with project bars
- Drag bars to reschedule
- Resize bars to adjust duration
Accessing the Gantt View
Step-by-Step: Switch to Gantt
- Open Scheduling from the sidebar
- Click Gantt in the toolbar view switcher
- The timeline loads with all scheduled projects
- DrillerDB remembers that you picked the Gantt view, and the zoom level you chose
Grouping the Timeline
The Gantt toolbar lets you group the timeline rows three ways: By Driller, By Status, or By Team. Each group becomes a labeled lane, and bars keep their team or driller color regardless of the grouping you pick. Dragging a bar slides the following jobs in the same lane when grouping by driller or team; status grouping does not slide other jobs. The hover note on a bar says Cascade on or Cascade off (status grouping).
Timeline Display
Timeline Elements
| Element | Description |
|---|---|
| Horizontal axis | Date scale, with weekends shaded |
| Lanes | One lane per crew, driller, or status, with its name pinned on the left |
| Bars | Project duration |
| Today line | Current date marker, updated every minute. The Today button scrolls back to it |
| Shaded lane days | Someone in that lane is out. A pending time-off request is hatched |
Zoom
Use the zoom buttons Quarter Day, Day, Week, and Month.
| Zoom | Scale Shows |
|---|---|
| Quarter Day | Six-hour blocks, with times to the hour |
| Day | One column per day |
| Week | A narrower column per day, grouped by week |
| Month | The narrowest columns, grouped by month |
Pick a zoom that fits the question. Use Month to see the whole season and Quarter Day when you need exact start times. DrillerDB remembers your choice.
Reading the Gantt Chart
Chart Structure
| Component | Shows |
|---|---|
| Lane | One crew, driller, or status. Jobs that overlap in time stack into extra rows inside the lane |
| Bar | One project |
| Bar position | Start date |
| Bar length | Duration |
| Bar color | The team's color, then the driller's color, then DrillerDB orange |
Bar Information
Hover a bar to see:
| Hover Element | Information |
|---|---|
| Customer name | Primary customer |
| Address | Job address |
| Scheduled date | Start date |
| Estimated duration | Expected length |
| Reminder | "Drag to reschedule. Right edge to resize." and whether cascade is on |
Click a bar, without dragging, to open its details panel.
Today Line
| Position | Meaning |
|---|---|
| Bars before line | Past/completed work |
| Bars at line | Current work |
| Bars after line | Future/upcoming work |
Rescheduling Projects
Drag to Reschedule
| Action | How |
|---|---|
| Move start date | Drag bar left/right |
| Move earlier | Drag bar to the left |
| Move later | Drag bar to the right |
Step-by-Step: Move a Project
- Click and hold on the project bar
- Drag left (earlier) or right (later)
- The bar snaps to whole days (to the hour in Quarter Day zoom)
- Release to drop it
- DrillerDB saves. If the save fails, a message reads "Reschedule failed" with the reason, and the bar goes back
Press Escape while dragging to cancel. Dragging works with a finger on a touch screen too.
Resize to Adjust Duration
| Action | How |
|---|---|
| Increase hours | Drag right edge further right |
| Decrease hours | Drag right edge to the left |
The resize handle is on the right edge of the bar only. To change the start, move the bar.
Step-by-Step: Resize a Project
- Position the cursor on the right edge of the bar
- The cursor changes to a resize arrow
- Click and drag to the new length
- Release to confirm
- Estimated hours update automatically
Resizing changes the project's estimated hours. When grouped by driller or team, the following jobs in the lane slide to fit the new duration.
Cascade Scheduling
How Cascade Works
When you group by driller or team, every later job in the same lane slides by the same amount you moved the bar, and lands on the next working day start.
| When You | Following Projects |
|---|---|
| Move project earlier | Slide earlier by the same amount |
| Move project later | Slide later by the same amount |
| Make project longer | Slide later |
| Make project shorter | Slide earlier |
Grouping By Status does not cascade. Only the bar you move changes.
The Gantt view does not check for double-booking. Review the schedule after a big move. See Conflict Detection.
Working with Teams
Team-Based View
| Element | Shows |
|---|---|
| One lane per team | Team's complete schedule |
| Team colors | Color-coded bars |
| Workload comparison | Visual capacity review |
Step-by-Step: Compare Team Workloads
- View all team lanes
- Compare bar density
- Identify teams with gaps (capacity)
- Identify teams with dense bars (busy)
- Consider rebalancing work
Navigation Controls
Moving Through Time
| Control | Action |
|---|---|
| Scroll horizontally | Move along timeline |
| Zoom buttons | Quarter Day, Day, Week, Month |
| Today button | Return to current date |
Keyboard Navigation
Click a bar to focus it, then:
| Shortcut | Action |
|---|---|
Left / Right | Move the bar earlier or later |
Shift + Left / Right | Shorten or lengthen the bar by one workday |
Visual Feedback
While you drag, the bar follows your pointer and the pointer shows a resize arrow on the right edge. If a save fails, an error message appears above the chart for a few seconds.
Performance Notes
For Large Schedules
| Challenge | Solution |
|---|---|
| Many projects | Scroll to navigate. Lanes and dates stay pinned |
| Long time range | Zoom out to Month for an overview |
Best Practices
| Practice | Benefit |
|---|---|
| Use zoom appropriately | Better visibility |
| Make one change at a time | Easier to see what a cascade did |
Troubleshooting
Bars not appearing?
- Check date range includes scheduled projects
- Check the All drillers and All statuses filters and the Search projects box
- Zoom out to see more of timeline
Can't drag bars?
- Ensure clicking on the bar itself
- Check for browser compatibility
- Try disabling browser extensions
Changes not saving?
- Look for the "Reschedule failed" message above the chart
- Check internet connection
Bars overlapping?
- Jobs that overlap in time stack in extra rows inside the lane. That is normal
- Check the dates, or move one job
Timeline scale wrong?
- Click a different zoom button
- Scroll to find projects
- Use the Today button to reset the view
