Gantt Diagram

The Gantt is described in natural language, using very simple sentences (subject-verb-complement).

Declaring tasks

Tasks defined using square bracket.

Duration

Their durations are defined using the last verb:

@startgantt
[Prototype design] lasts 15 days
[Test prototype] lasts 10 days
-- All example --
[Task 1 (1 day)] lasts 1 day
[T2 (5 days)] lasts 5 days
[T3 (1 week)] lasts 1 week
[T4 (1 week and 4 days)] lasts 1 week and 4 days
[T5 (2 weeks)] lasts 2 weeks
@endgantt

A week is a synonym for how many non-closed days are in a week. So if you specify Saturday and Sunday as closed, a week will be equivalent to 5 days

Start

Their beginning are defined using the start verb:

@startuml
[Prototype design] lasts 15 days
[Test prototype] lasts 10 days

Project starts 2020-07-01
[Prototype design] starts 2020-07-01
[Test prototype] starts 2020-07-16
@enduml

End

Their ending are defined using the end verb:

@startuml
[Prototype design] lasts 15 days
[Test prototype] lasts 10 days

Project starts 2020-07-01
[Prototype design] ends 2020-07-15
[Test prototype] ends 2020-07-25

@enduml

Start/End

It is possible to define both absolutely, by specifying dates:

@startuml

Project starts 2020-07-01
[Prototype design] starts 2020-07-01
[Test prototype] starts 2020-07-16
[Prototype design] ends 2020-07-15
[Test prototype] ends 2020-07-25

@enduml

One-line declaration (with the and conjunction)

It is possible to combine declaration on one line with the and conjunction.

@startuml
Project starts 2020-07-01
[Prototype design] starts 2020-07-01 and ends 2020-07-15
[Test prototype] starts 2020-07-16 and lasts 10 days
@enduml

Adding constraints

It is possible to add constraints between tasks.

@startgantt
[Prototype design] lasts 15 days
[Test prototype] lasts 10 days
[Test prototype] starts at [Prototype design]'s end
@endgantt

@startgantt
[Prototype design] lasts 10 days
[Code prototype] lasts 10 days
[Write tests] lasts 5 days
[Code prototype] starts at [Prototype design]'s end
[Write tests] starts at [Code prototype]'s start
@endgantt

Short names

It is possible to define short name for tasks with the as keyword.

@startgantt
[Prototype design] as [D] lasts 15 days
[Test prototype] as [T] lasts 10 days
[T] starts at [D]'s end
@endgantt

Customize colors

It is also possible to customize colors with is colored in.

@startgantt
[Prototype design] lasts 13 days
[Test prototype] lasts 4 days
[Test prototype] starts at [Prototype design]'s end
[Prototype design] is colored in Fuchsia/FireBrick
[Test prototype] is colored in GreenYellow/Green
@endgantt

Completion status

You can set the completion status of a task.

@startgantt
[foo] lasts 21 days
[foo] is 40% completed
[bar] lasts 30 days and is 10% complete
@endgantt

Milestone

Milestone

You can define Milestones using the happens verb.

@startuml
[Themenfindung] lasts 10 days
[Themenfindung] is colored in CornflowerBlue
[Anforderungsanalyse] lasts 10 days
[Beginn Projektplanung] lasts 10 days
[Beginn Projektplanung] starts at [Anforderungsanalyse]'s end
[Aufgaben verteilen] happens at [Beginn Projektplanung]'s end
[Setup assembly line] lasts 12 days
[Setup assembly line] starts at [Beginn Projektplanung]'s end
@enduml

You can define Milestones using the happen verb.

Relative milestone (use of constraints)

@startgantt
[Test prototype] lasts 10 days
[Prototype completed] happens at [Test prototype]'s end
[Setup assembly line] lasts 12 days
[Setup assembly line] starts at [Test prototype]'s end
@endgantt

Absolute milestone (use of fixed date)

@startgantt
Project starts 2020-07-01
[Test prototype] lasts 10 days
[Prototype completed] happens 2020-07-10
[Setup assembly line] lasts 12 days
[Setup assembly line] starts at [Test prototype]'s end
@endgantt

Milestone of maximum end of tasks

@startgantt
[Task1] lasts 4 days
then [Task1.1] lasts 4 days
[Task1.2] starts at [Task1]'s end and lasts 7 days

[Task2] lasts 5 days
then [Task2.1] lasts 4 days

[MaxTaskEnd] happens at [Task1.1]'s end
[MaxTaskEnd] happens at [Task1.2]'s end
[MaxTaskEnd] happens at [Task2.1]'s end

@endgantt

[Ref. QA-10764]

Hyperlinks

You can add hyperlinks to tasks.

@startgantt
[task1] lasts 10 days
[task1] links to [[http://plantuml.com]]
@endgantt

Calendar

You can specify a starting date for the whole project. By default, the first task starts at this date.

@startgantt
Project starts the 20th of september 2017
[Prototype design] as [TASK1] lasts 13 days
[TASK1] is colored in Lavender/LightBlue
@endgantt

Coloring days

It is possible to add colors to some days.

@startgantt
Project starts the 2020/09/01 

2020/09/07 is colored in salmon
2020/09/13 to 2020/09/16 are colored in lightblue

[Prototype design] as [TASK1] lasts 22 days
[TASK1] is colored in Lavender/LightBlue
[Prototype completed] happens at [TASK1]'s end
@endgantt

Changing scale

You can change scale for very long project, with one of those parameters:
  • printscale
  • ganttscale
  • projectscale
and one of the values:
  • daily (by default)
  • weekly
  • monthly
  • quarterly
  • yearly

(See QA-11272, QA-9041 and QA-10948)

Close day

It is possible to close some day.

@startgantt
project starts the 2018/04/09
saturday are closed
sunday are closed
2018/05/01 is closed
2018/04/17 to 2018/04/19 is closed
[Prototype design] lasts 14 days
[Test prototype] lasts 4 days
[Test prototype] starts at [Prototype design]'s end
[Prototype design] is colored in Fuchsia/FireBrick
[Test prototype] is colored in GreenYellow/Green
@endgantt

Then it is possible to open some closed day.

@startgantt
2020-07-07 to 2020-07-17 is closed
2020-07-13 is open

Project starts the 2020-07-01
[Prototype design] lasts 10 days
Then [Test prototype] lasts 10 days
@endgantt

Definition of a week depending of closed days

A week is a synonym for how many non-closed days are in a week, as:

@startgantt
Project starts 2021-03-29
[Review 01] happens at 2021-03-29
[Review 02 - 3 weeks] happens on 3 weeks after [Review 01]'s end
[Review 02 - 21 days] happens on 21 days after [Review 01]'s end
@endgantt

So if you specify Saturday and Sunday as closed, a week will be equivalent to 5 days, as:

@startgantt
Project starts 2021-03-29
saturday are closed
sunday are closed
[Review 01] happens at 2021-03-29
[Review 02 - 3 weeks] happens on 3 weeks after [Review 01]'s end
[Review 02 - 21 days] happens on 21 days after [Review 01]'s end
@endgantt

[Ref. QA-13434]

Simplified task succession

It's possible to use the then keyword to denote consecutive tasks.

@startgantt
[Prototype design] lasts 14 days
then [Test prototype] lasts 4 days
then [Deploy prototype] lasts 6 days
@endgantt

You can also use arrow ->

@startgantt
[Prototype design] lasts 14 days
[Build prototype] lasts 4 days
[Prepare test] lasts 6 days
[Prototype design] -> [Build prototype]
[Prototype design] -> [Prepare test]
@endgantt

Working with resources

You can affect tasks on resources using the on keyword and brackets for resource name.

@startgantt
[Task1] on {Alice} lasts 10 days
[Task2] on {Bob:50%} lasts 2 days
then [Task3] on {Alice:25%} lasts 1 days
@endgantt

Multiple resources can be assigned to a task:

@startgantt
[Task1] on {Alice} {Bob} lasts 20 days
@endgantt

Resources can be marked as off on specific days:

@startgantt
project starts on 2020-06-19
[Task1] on {Alice} lasts 10 days
{Alice} is off on 2020-06-24 to 2020-06-26
@endgantt

Separator

You can use -- to separate sets of tasks.

@startgantt
[Task1] lasts 10 days
then [Task2] lasts 4 days
-- Phase Two --
then [Task3] lasts 5 days
then [Task4] lasts 6 days
@endgantt

Complex example

It also possible to use the and conjunction.

You can also add delays in constraints.

@startgantt
[Prototype design] lasts 13 days and is colored in Lavender/LightBlue
[Test prototype] lasts 9 days and is colored in Coral/Green and starts 3 days after [Prototype design]'s end
[Write tests] lasts 5 days and ends at [Prototype design]'s end
[Hire tests writers] lasts 6 days and ends at [Write tests]'s start
[Init and write tests report] is colored in Coral/Green
[Init and write tests report] starts 1 day before [Test prototype]'s start and ends at [Test prototype]'s end
@endgantt

Comments

As is mentioned on Common Commands page:
Everything that starts with simple quote ' is a comment.

You can also put comments on several lines using /' to start and '/ to end.
(i.e.: the first character (except space character) of a comment line must be a simple quote ')

@startgantt
' This is a comment

[T1] lasts 3 days

/' this comment
is on several lines '/

[T2] starts at [T1]'s end and lasts 1 day
@endgantt

Using style

Without style (by default)

@startuml
[Task1] lasts 20 days

  memo2 ...
  explanations1 ...

[Task2] lasts 4 days

Clean style

With style, you can also clean a Gantt diagram (showing tasks, dependencies and relative durations only - but no actual start date and no actual scale):
