Hi Dmitry !!
I made the changes you recommended to the “chart.properties” file, but nothing changed on the screen. I uninstalled version 2.8.11 - r2396, and reinstalled version 2.8.1 - r2024, and the tasks in the timeline are displayed correctly (see attached photo).
Check the file “chart.properties” in version 2.8.1 - r2024, and it is exactly the same as the file in version 2.8.11 - r2396: the lines say “text” and it works correctly.
As I received the new versions, after 2.8.1 - r2024, …, I encountered certain problems, and for that reason I never updated the version that worked correctly. I do not know exactly from which version this problem is happening that I am mentioning to you now. Since 2016 I use version 2.8.1 - r2024.
Could you help me? Thanks!!
