I am using Gantt chart to show the planning of something that were a "discrete timestep" is not a day, but just some undefined thing. So having it numbered like in the duration example(https://plantuml.com/en/gantt-diagram) would be what I want.
But there's a problem: I can't find a way to start a task on a date that's not "day" 1 or the end of another task. So basically I would like to write something along
[phase 1] lasts 10 days
[phase 2]lasts 4 days and starts at day 2
But the latter does not work.
Is there already some way to achieve that or is that a "missing" feature? Or does somebody see a workaround (like using dates but keeping the bottom and top at using 1,2,3,...)
