Add task start date and finish date to GANTT label

Question

Hello, I would like to propose a feature for the plantuml GANTT charts:

Add an option to show the calculated start and end date of every task in the task label.

This could optionally also be shown at the left ot the chart in addition to the current behaviour.

Final proposed behaviour:

• There is a new section left of the main chart showing per task row: the task name, start date and end date. Optional: also the duration of a task can be shown in this left area.
• Inside the main chart the task name is shown, and optionally again the start and/or end date, with start date shown left and finish date showing right of the task name label and the chart bar.

I prefer to present the date always in the format YYYY-MM-DD. This should be adjustable of course.

Rationale:

I work with multi-year project plans, and the daily print scale makes the chart very large. So I am primarily using a weekly or monthly print scale. But with this less detailed scale the information of exact start and end dates is lost and not shown in the current behaviour. To be very precise in project communication I always need exact start and end dates for every single task, shown on the same page like the chart, also in weekly or yearly print scales.

Thanks and best regards

Thank you for the detailed suggestion, this is a very good idea.

We are currently actively working on the Gantt engine, in particular on extending it to handle finer time precision (hours, minutes, seconds). Your proposal fits very well within this ongoing effort.

We will add this idea to our backlog and consider it as part of the current Gantt refactoring work.

Thank you for taking the time to share this, and thank you for your patience.
