Relationship View
Relationship View shows your timeline content in a vertical table format.
- Events are shown in rows in chronological order.
- Entities are shown in columns across the top of the screen.
- The intersection between rows and columns indicates any relationships that exist between events and entities.
- Time is not represented linearly in Relationship View, but event dates and entity ages will help you keep track of time.
Column Selection
Relationship View shows columns for a single entity type at a time. To choose which entity type should be used for the columns, simply tap on the entity type name above the list of events, and then select a new entity type from the popover: 
Depending on the width of your timeline and the number of columns displayed, you may wish to expand or collapse the width of the event column. To do this, click on the small > arrow at the top of the Relationship View.
For screen space reasons, this behaves differently to the Desktop version, where you are able to view columns from multiple different entity types, and choose to show or hide individual entities.
Although the iPad app doesn't let you compare across entity types via columns, you can still use groups via the Side Bar to filter events for an entity of a different type, allowing comparisons to be made.
Modifying Relationships
Relationships represent a connection between an event and an entity. This may represent a particular person was present at an event, or an event belongs to a particular story arc or project.
Relationships are many-to-many, meaning each event can have relationships with multiple entities, and each entity may have relationships with multiple events.
When specifying a relationship, you also specify the role that the entity fulfils for that event. Many entity types may only allow a single role, but some types may have multiple roles – for instance, a person may be a participant in an event, or just a witness. Roles are defined in the timeline’s template.
The intersection between event rows and entity columns marks the relationships between those items. If a relationship exists between an event and entity, an icon will be shown at the intersection. If there is no relationship between an event and entity, the intersection will be left empty.
Tapping on an intersection allows you to add or remove relationships. A popover will be shown which allows you to choose the Role that the entity should fill for this event. Choosing None will remove any relationship that currently exists.
Each role is represented by a different icon in the Relationship View. You can choose which icon is used for a role via Timeline Settings.
