Gantt Chart - <time> after <taskId> - for setting delayed start #818

Open mike-usa opened 5 years ago

mike-usa commented 5 years ago

As described in the following comment (https://github.com/knsv/mermaid/issues/552#issuecomment-356012310):

I need a delay, like start apple 1 week after banana; both beginning and ending.

Consider the following Gantt chart:

gantt
    title A Gantt Diagram
    dateFormat  YYYY-MM-DD
    axisFormat %m/%d/%Y

    section Phase I#colon; A
    First    : first, now, 1d

    section Phase I#58; B
    Second   : second, after first, 12h

I'd expect to be able to be able to perform the second task 1 day after first task concludes via 1d after first. Perhaps there is already a way to perform an offset/delay buffer that hasn't been documented?

I've unsuccessfully attempted to create a hidden buffer task to use as the start date, which did not work because I could not control the styling (it was still visible); below should help exemplify my effort:

section Phase I#colon; A
First    : first, now, 1d
Break    :hidden break1, after first, 1d
Second   : second, after break1, 12 h

Please let me know if this needs further clarification and feel free to use the demo for a working reference.

I understand what you are after. This is a good idea! Not in place though but I will add it to the project backlog. I am hoping for a larger team moving forward to be able to implement things like this. #866

I would also like to see this feature. Commenting to revive as a potential TODO.

agreed I like this feature

RCarvalho13 commented 1 year ago

The addition of this feature would be great. This would be very useful for the definition of deliverables, which usually have a due date after the completion of the task.

Yes I agree, this would be nice. To build some simple schedules it is a critical feature to me, to let a task start two weeks after the beginning of a previous task. This is a Start-Start dependency with 2 week "lag", not a Finish-Start dependency like the default after behaviour.

Chiming in on this too - it's more or less necessary for projects beyond the most basic.
