Timeline

Timeline groups dated history into Begins, Ends, and Changes. Nodes begin when they come into existence. Relationships have beginnings and endings. Property and text version boundaries appear under Changes; multiple facts changing on the same element at the same tick produce one entry.

Death and other states are ordinary properties. A death property can produce a change entry, while the node remains in history.

Read transitions

Select a transition to open the affected node or relationship. A marker shows the current viewed time within the chronology.

Labels between history dates show elapsed time in the selected calendar’s largest completed unit. Over 4 years, for example, means smaller units remain. Without a calendar, or if its duration cannot be calculated, the label uses timeline ticks.

Longer gaps receive more space. Large gaps have a dashed line and Time gap compressed label; spacing is not a proportional time scale. Gaps are measured between the history dates shown by the current filter, even when the viewed-time marker falls between them. They do not imply that nothing happened in the world.

Busy date groups initially show a smaller set of transitions. Use Show more to reveal the rest, then collapse the group when finished.

Filter the timeline

Open the filter control and include Nodes, Relationships, or both. At least one category remains enabled, so the timeline cannot be filtered to an empty category set by accident.

The page remembers filters, expanded groups, and scroll position during the current app session.

Move through history

Use the earlier and later page actions to load transitions beyond the current window. A failed page shows a retry action without discarding already loaded history.

Choose the time action beside a date group to set that date as the project’s current viewed time. The global sidebar control updates, and other time-aware pages will now project the graph at that moment.

See Project time for activating time, Nodes and relationships for starts and relationship periods, and Properties and notes for recording state changes.
