Hello, with
https://www.dokuwiki.org/plugin:structgantt I'm struggeling also.
What I got until now is:
goto "admin -> Struct Schema Editor" and create a new schema (could be named timemachine as in the example) schema-type: "Page Schema"
At the bottom: label -> "label Timemachine" -> save
Now include 3 Fields: Taskname (Text), Start (Datetime), End (Datetime) as described here:
* Add a Field "Taskname" Type: Text, Label "fieldlabel Taskname" -> Save
* Add a Field "Start" Type: Datetime, Label "fieldlabel Start" -> Save
* Add a Field "Stop" Type: Datetime, Label "fieldlabel Stop" -> Save
goto "admin Struct Schema Assignments"
Page/Namespace: timemachine -> Schema: timemachine -> Add
-> create a page timemachine (you should now how to do it ;-) )
At the Bottom you see the fields of timemachine
I'm on my way but not finished, yet.
-> What to do now? How to add tasks to the Gantt chart?
-> shall I add a schema for each task?
