Set up an object
Drag Tm Relationship Explorer from Custom objects to the sheet. Add up to five dimensions and one measure. In Data roles, select a mode in Chart type, then map one field for each role.
Source and Target are required in every mode. Weight sets the size of a relationship. Category colors a relationship. Stage is required for Alluvial. Time shows one snapshot at a time.
Data detail states what one row of the data is. Use Edge for one row per source and target pair, which is the default for Chord, Network, Arc, and Adjacency matrix. Use Edge-stage for Alluvial. Maximum rows to request defaults to 5,000.
