Gantt Chart Vertical Separators

+1 vote
asked Jul 11, 2022 in Question / help by systemsincode

Is there any way to add vertical separators to Gantt Charts?

I want to make it easy to see where a sprint starts by having a vertical line to show the alignment but can't:

Is it possible?

ps. I am using relative gantt (not dates) as showing general pattern not date specific...

This is a good idea!

With last snapshot, you can use the following syntax:

@startgantt

[task1] lasts 1 week
[task2] starts 20 days after [task1]'s end and lasts 3 days

Separator just at [task1]'s end
Separator just 2 days after [task1]'s end

Separator just at [task2]'s start
Separator just 2 days before [task2]'s start

@endgantt

Is this what you were expecting? We are not satisfied by the syntax, so if someone has a better suggestion, please make some suggestion. Thanks!

Hello,

It's a good function !

And why not with a fixed date ?  (like milestone's date)

@startgantt

Project starts 2022-12-01

[task1] lasts 1 week
[task2] starts 20 days after [task1]'s end and lasts 3 days

Separator just at 2022-12-15

Hello E., and all,

For that a possible workaround is to add a dummy Milestone, as:

@startgantt
Project starts 2022-12-01

[task1] lasts 1 week
[task2] starts 20 days after [task1]'s end and lasts 3 days

'Separator just at 2022-12-15
[ ] happens at 2022-12-15
[ ] is deleted
Separator just at [ ]'s end
@endgantt

But that is not so fun...cheeky

Then @PlantUML team, here is the wanted feature:

  • Allow separator at fixed date.

Regards.
