Tooltip in Gantt Chart

Hi Everybody,

i hope someone can help me.

I had an Gantt Chart. This Gantt shows for example Absence from employees.

When it is a absence about one complete day it looks finde. But when its a absence for example the halff day from 12 am till 3 pm than i will see the absence but the tooltip and the event is not there!

Have everybody an idea how can i solve this problem?

Thanks a lot.

Best Regards,

Markus
