Types of Graphics Objects

Introduction

There are two basic types of graphics objects:

• Core graphics objects — Used by high-level plotting functions and by composite objects to create plot objects

• Composite objects — Composed of core graphics objects that have been grouped together to provide a more convenient interface

Composite objects form the basis for four subcategories of graphics objects.

• Plot objects — Composed of basic graphics objects, but enable properties to be set on plot object level

• Annotation objects — Exist on a layer separate from other graphics objects

• Group objects — Create groups of objects that can behave as one in certain respects. You can parent any axes child object (except light) to a group object, including other group object.

• UI objects — User interface objects are used to construct graphical user interfaces.

Graphics objects are interdependent, so the graphics display typically contains a variety of objects that, in conjunction, produce a meaningful graph or picture.
