Timelines Timelines display a linear calendar of tasks, such as incidents and change requests, defined by their start and end dates. Each task on the timeline is represented by a span, which is displayed as a horizontal bar and may have distinctive color coding. Each span has a label and can have tooltip text containing additional information about the task. You can also change the calendar's perspective for a more granular view of the data.
