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

asked Dec 23, 2022 in Bug by Étienne21 (120 points)

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

If not please clarify.

Best answer

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?

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.
