What is a Gantt chart?

A Gantt chart is a timeline view of a project where every task is a bar showing when it starts and finishes, and lines between bars show which tasks depend on others. Orangescrum gives you an interactive Gantt chart you can drag to reschedule, with dependencies, milestones, and critical path, so you can see the effect of a change before you commit to it.

The problem

Why plans stop being true

The plan lives in a spreadsheet
It is accurate the day it is made and wrong a week later.
✓ A live chart built from the same tasks your team is working on.
Nobody sees the knock on effect
One task slips and nobody realises what else moves.
✓ Dependencies show exactly what a delay pushes back.
Two sources of truth
The timeline says one thing, the board says another.
✓ The Gantt chart and the board are the same tasks in different views.
What you get

A timeline that stays accurate

Every control on the Gantt page, grouped by what you are doing: viewing the timeline, linking work, editing the plan, filtering it down, and getting it out.

01Timeline

  • Interactive chart

    Every task is a bar on one timeline, arranged by project and milestone the way the project is already structured.

  • Zoom levels

    Move between hour, day, week, month and year with quarter scales to see fine detail or the whole span.

  • Zoom to fit

    Fit the full project span to the width of the screen in one click.

  • Working days

    Weekends are shaded using the working week set for your company, and a marker shows where today sits.

  • Milestones

    Mark the dates that matter so progress is measured against real checkpoints.

  • Rolled up dates

    A milestone or project bar spans the earliest start and the latest finish of the work inside it.

02Dependencies

  • Four link types

    Link tasks finish to start, start to start, finish to finish, or start to finish.

  • Draw links on the chart

    Create and remove links by dragging between bars, and they are saved with the rest of the plan.

  • Dates move together

    Move a predecessor and the tasks linked after it shift along the chain with it.

  • Critical path

    Orangescrum calculates the chain of linked tasks that sets your end date and highlights it on the chart.

  • Critical flag on task lists

    The same critical marker shows on tasks in the normal task list, not only on the Gantt page.

03Editing

  • Drag to reschedule

    Move or resize a bar to change the start and due date instead of typing into a form.

  • Indent and outdent

    Change a task's parent from the toolbar to restructure the plan without opening each task.

  • Multi select actions

    Select several bars and indent them, nudge them a day forward or back, or delete them together.

  • Undo and redo

    Step back through changes before you save, and get warned if you try to leave with unsaved work.

  • Full task editor

    Set title, description, parent, assignee, priority, milestone, task type, status and dates from the chart.

  • Create work from the chart

    Add new tasks and milestones on the timeline and they become real tasks in the project.

  • Delete with permission

    Remove tasks from the chart. In self-hosted, deletion honours the Delete Task and Delete All Task permissions.

  • Save the plan in one action

    Every date change, new link and deletion is posted together when you save the plan.

  • Status and automation

    Change a task's custom status on the chart and your workflow automation runs as it would anywhere else.

04Grid

  • Task columns

    Task name, start date, due date, duration in days, estimated hours, assignee and close date sit beside the timeline.

  • Hide the task list

    Collapse the grid so the timeline gets the full width of the screen.

05Filters

  • By assignee

    Narrow the chart to the people you care about, one or several at a time.

  • Show or hide completed

    Keep finished work out of the view until you want to see it.

  • By epic and sprint

    Self-hosted adds epic and sprint filters, so a large plan can be cut down to one slice of delivery.

06Export

  • PDF and image

    Export the chart as a PDF or a PNG for people who do not use Orangescrum.

  • Rendered on your server

    In self-hosted the export is queued and drawn on the server, with a progress indicator, and it survives a page reload.

07Access

  • View and edit are separate

    Viewing the chart and editing it are different permissions, so read only access to the plan is possible.

  • Unlimited users

    Everyone who needs to see the plan can, because there is no per seat cost.

How it works

How to build a plan

1
Add your tasks
Start from the tasks already in your project, or add the plan directly.
2
Set the dates
Drag bars on the timeline instead of typing dates into a form.
3
Link dependencies
Connect the tasks that have to happen in sequence.
4
Track and adjust
As work moves, the chart shows what has slipped and what it affects.

Frequently asked questions

Gantt chart FAQ

Does Orangescrum have Gantt charts?

Yes. Orangescrum includes an interactive, drag and drop Gantt chart with task dependencies, milestones, and critical path, built from the same tasks your team works on day to day.

Which editions include Gantt charts?

Gantt charts are available in the Cloud edition on every paid plan and in the Self-Hosted edition. Critical path analysis is on the Premium plan in Cloud and included in Self-Hosted.

Can I drag tasks to change dates?

Yes. You move or resize a bar on the timeline and the dates update. Where tasks are linked, dependent work adjusts too.

What is critical path?

The critical path is the chain of dependent tasks that determines your project end date. If anything on that chain slips, the project slips, so it tells you where a delay actually matters.

Can I use Gantt and Kanban together?

Yes. The Gantt chart and the board are two views of the same tasks, so a Scrum or Kanban team can still have a timeline for stakeholders.

Can I export the chart?

Yes. You can export as PDF or an image to share with people who do not use Orangescrum. In the self-hosted edition, large exports run as a background job so your browser is not tied up.

Does it cost more per person to give everyone access?

No. Every Orangescrum plan includes unlimited users, so you can give the whole team and your clients access to the plan without the bill changing.

Is the Gantt chart in the open source edition?

The Community Edition includes projects, tasks, and Kanban boards. Gantt charts are available in the Cloud and Self-Hosted editions.

Build a plan that stays true

Gantt charts are in the Cloud and Self-Hosted editions. Every plan includes unlimited users, with no per seat pricing.
