It is possible to run a report that includes a chart of your cumulative absences for a specific period of time.
To do so:
1. Click on the Calendar section
2. Click on My absences
3. Click on Reports
4. Choose your report start and end date and click on Apply
An absence report, by absence type (congress, vacation, personal, training, etc.) will then be generated and you will see the total number of absences taken for each absence category for a specific period of time.
