Graphics Object Creation Functions

Each graphics object (except the root object) has a corresponding creation function, named for the object it creates. This table lists the creation functions.

Function	Object Description
axes	Rectangular coordinate system that scales and orients axes children image, light, line, patch, surface, and text objects.
figure	Window for displaying graphics.
image	2-D picture defined by either colormap indices or RGB values. The data can be 8-bit or double precision data.
light	Directional light source located within the axes and affecting patches and surfaces.
line	Line formed by connecting the coordinate data with straight line segments, in the sequence specified.
patch	Polygonal shell created by interpreting each column in the coordinate matrices as a separate polygon.
rectangle	2-D filled area having a shape that can range from a rectangle to an ellipse.
surface	Surface created with rectangular faces defined by interpreting matrix elements as heights above a plane.
text	Character string located in the axes coordinate system.
uicontextmenu	Context menu that you can associate with other graphics object.
uicontrol	Programmable user-interface device, such as pushbutton, slider, or listbox.
uimenu	Programmable menu appearing at the top of a figure window.

All object creation functions have a similar format.

• handle = function('propertyname',propertyvalue,...)
  

You can specify a value for any object property (except those that are read only) by passing property name/property value pairs as arguments. The function returns the handle of the object it creates, which you can use to query and modify properties after creating the object.
