This is a Y-shaped matrix diagram. The Y-shaped diagram relates three groups of items that are all related to each other and exist in a circular flow. Here group A, group B, and group C are connected and related to each other (i.e., A ← → B ← →C← →A). These relationships are depicted in a circular diagram. Use the Y-shaped matrix when you need to compare three closely related groups. It can also be used as a practical simplification of the C-shaped matrix. The below example depicts the relation between 3 such groups (i.e. Tasks, Shifts, and location). For more examples, please check out our edrawMax template gallery.
