If you only want to display the data, how about using the Charts app for this:
If you also want to edit the data, you can present it using a list view. One person per object, which has the dates as attributes. Placed below each other.
Dear Denzin,
The Calendar widget https://appstore.home.mendix.com/link/app/248/ contains a scheduler (requires an third party license) https://fullcalendar.io/docs/premium
Does that fit your needs?
Cheers, Andries
