Events is a default label category. It allows you to view date ranges of events alongside documents in your Chronology. The Events view can help you contextualize how documents are related to particular events, and how events are related to each other.
Events labels, once created, automatically appear as markers within the document timeline if Events view is toggled on. They can additionally be applied as labels to a document; however, this is not necessary for the event to appear within the timeline. Since the event label must be associated with a date range, the Chronology will automatically recognize which documents do or do not fall within the date range and display the event marker appropriately.
Creating an event label
After creating a new event label, you will be required to enter a date range for the event. You can either use the date selector to pick your date range, or type the date range into the input box. When you've entered the date range, click Save.
If the Events view in the toolbar is not turned on, nothing will change in your document timeline at this point. Your new event will appear under the Events label category, greyed out to indicate that the event is not applied to a document. Removing an event label is the same as removing any other label. You cannot delete the Event category.
Viewing event markers in your document timeline
To display events in your timeline, the timeline must be sorted by date. By default, Chronologies are sorted from newest to oldest by date. Click the Event icon in the toolbar to display the event markers in your document timeline.
Light blue event markers will appear in the central table of entries.
- Event header: This displays the event name, date range, description, and relevance. You can click any of these fields to edit them.
- Event marker: Markers span across the vertical distance of the documents that fall within the date range of the event. This only shows up if there are documents that fall within the range of a particular event. Otherwise, only the event header will appear.
Only documents that fall within the time range of an event will appear within the event marker, including documents that are not labeled with the event. If there are multiple events that have overlapping date ranges, those events will cascade vertically along the left side of the timeline.
The length of event markers are proportional to the number of documents that fall within an event, and not the date range of the event. For example, an event that lasts 2 days with 20 documents will have a longer event marker than an event that lasts 30 days with only 5 documents.
If no documents fall within an Event's date range, then the event will simply be represented as an Event header, horizontally as a row in the timeline.
Labeling documents with events
In addition to viewing event headers and markers, you can label each document with an event.
Even if the document falls outside the event date range, you might still want to associate it with the event. For example, some documents might be related to an event, but were not generated during the time range of the actual event. You can learn more about adding labels to documents in this article.
Filtering by event
To filter documents by an event date range, simply click the checkbox next to the event name in the label panel. The timeline will adjust so that only the documents (if applicable) that fall into the date range of your event will appear.
If there are no documents that fall within the event's date range, then the event will be greyed out in the panel, and you will not be able to filter by it.
Deleting an event from the timeline
To delete an event from the timeline, hover over the event header and a trashcan icon will appear. Click the trashcan and confirm deletion. In addition to the timeline view, you are also deleting the event label itself. The label will be removed from any documents in the Chronology that it's applied to.
