Timeline Tool

How to use this tool

The timeline tool lets you explore Portal content by year and compare results for different searches.

Search for content. It is possible to filter by keyword, content type or theme (all are optional).

Travel through time. TODO (update).

View results. The result index’s peaks represent the amount of Portal content by year. The result canvas (left) displays individual events by year. Click on an event to view details.

Compare results for two searches. A different color is assigned to each search. Show or hide a search by checking the colored boxes above the index. Click edit to modify or delete a search.
