Hi PlantUML community,
it seems, the Gantt-Diagram header with several lines doesn't work properly.
I tried the
header
line 1
line 2
line 3
endheader
combination. This results in an interpreter error. The corresponding legend definition works properly, however.
Can you please have a look at it? - I tried it with the latest version of plantuml, i.e., 1.2025.0.
Best
