Verticals separators in gantt chart don't appear under certain conditions

Question

Hello,

I notice that under certain conditions, separators in gantt chart do not appear.

With this code :

@startgantt
Project starts 2022-12-01
projectscale monthly zoom 3

[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

@endgantt

I obtain (without separators) :

If I take off one of the two lines :

Project starts 2022-12-01
projectscale monthly zoom 3

It works

Strange, no ?

Regards

@startgantt
Project starts 2022-12-01
projectscale weekly zoom 3

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

I think one of the 2 diagrams I just posted shows it working...

If not please clarify.

Answer 1

Is this due to the "projectscale monthly"?

Your tasks are all happening inside a single month, so this is what I would have expected, am I missing something?

Comments

Thanks, but it's not the right track... I can add some task during more a month, that doesn't change anything.

And if I take off only the "Project starts 2022-12-01" line, and leave the "projectscale monthly" line, it works.

Happy chrismas !

Yes...
But even with "projectscale monthly"
it would be nice to have the separators (proportionally in the month)...

Like coloured day , as:

@startgantt
Project starts 2022-12-01
projectscale monthly zoom 3

[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

2022-12-09 is colored in red
@endgantt

The big issue is if there are a lot of separator on a specific month...

Regards.

This should be now fixed in V1.2023.0.

Tell us if you find other issues!

Hi Plantuml,

This should be now fixed in V1.2023.0.

Sorry for the question, but:

• What is fixed?
• It seems there are some regressions...

FYI: We observed always this issue on 1.2023.11b2:

@startgantt
Project starts 2022-12-01
projectscale monthly zoom 3

[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

@endgantt

Thanks for a precision,

Regards,
Th.
