Handle Graphics

When you use a plotting command, MATLAB creates the graph using various graphics objects, such as lines, text, and surfaces (see Graphics Objects for a complete list). All graphics objects have properties that control the appearance and behavior of the object. MATLAB enables you to query the value of each property and set the value of most properties.

Whenever MATLAB creates a graphics object, it assigns an identifier (called a handle) to the object. You can use this handle to access the object's properties. Handle Graphics is useful if you want to

• Modify the appearance of graphs.
• Create custom plotting commands by writing M-files that create and manipulate objects directly.
