Viewing leave applications in a table form may be useful for reporting or answering general queries, as discussed in Detailed Leave Taken Report. However, if you want to see who is on Leave in a particular time-period, visual calendar may suit better your needs.
Timeline
By going to Leave Management and clicking on the Timeline tab, you are able to see the Timeline as shown in the below screenshot.
You will be able to see a list of all employees and a calendar of days in which leave is applied for. Clicking on the top bar will expand the calendar to the whole month. You are also able to edit a leave application by double-clicking any leave bar.
