Link Line Mode
There are 3 modes (GC.Spread.Sheets.GanttSheet.TaskBarLinkMode):
toEnd
toTop
noLinks
Taskbar Height
You can change the taskbar height with a specific number:
Date Format
If you add text to the taskbar, you can change its display formats.
Available formatters:

"yy/m/dd hh:mm"
"yy/m/dd"
"yyyy/m/dd"
"yyyy mmmm dd hh:mm"
"yyyy mmmm dd"
"mmm dd hh:mm"
"'yy mm dd"
"mmmm dd"
"mmm dd"
"ddd yy/m/dd hh:mm"
"ddd yy/m/dd"
"ddd yy mm dd"
"ddd hh:mm"
"ddd mm dd"
"ddd m/dd"
"ddd dd"
"m/dd"
"dd"
"hh:mm"

The actual task duration is not always whole days, so there is an option that will round these bars to whole days:
