Teacup Group
Teacup Groups are a container for Teacups so that all data is consistent across the teacups in the group. The Teacup Group defines the slots to use, where they are located, the size of the bars in the teacup, and the fonts for the label, axis, and text items. Teacup Groups can have bounding boxes, text items, and markers that are displayed for each teacup. In addition, a Teacup Group can have a Teacup legend to provide a key. See Teacup Legend and Instructions for Creating a Teacup Diagram for additional information.
