The Markdown Mermaid Diagram team added a new requested feature for a Gantt diagram - the displayMode: compact option.
Yet, using it on Joplin with the recommended syntax leads to an error:
---
displayMode: compact
---
gantt
title A Gantt Diagram
dateFormat YYYY-MM-DD
section Section
A task :a1, 2014-01-01, 30d
Another task :a2, 2014-01-20, 25d
Another one :a3, 2014-02-10, 20d
Can you update the Mermaid version in Joplin, so this feature will work?
Thank you for your job. Have a nice day!
