Hi, 

Our xamSchedule control does have Journal activities.   You may want to review the following documentation.

And there is a sample in the Feature Browser that demonstrates adding Appointments, Tasks and Journal entries.  You can find the Schedule View Customizations sample in the XamSchedule's Display section of our Feature Browser.  You’ll see some journal entries that are a soft yellow/orange color. 

Please let me know if you have any questions.
