Family envelopes
Display bubble-like envelopes around the records belonging to each material family on a chart. You can choose which envelopes to display and their color, or define custom groups of records to display this way.
There are two types of family envelope: system and custom.
System envelopes are the default envelopes for each data table, and represent material families. You may edit their name and display color, but you cannot edit their contents or delete them.
Custom envelopes can be added to selection projects. They behave in the same way as system envelopes, except you can define which records belong to them and delete them.
Note: Family envelopes are only available on bubble charts, and do not
apply any selection criteria.
