The objects involve graphics primitives like lines and text, and also the axes used to orient the objects. These objects are organized hierarchically, and there are properties related with each object. This is the base of object-oriented programming: objects are organized hierarchically (example, a parent comes before its children in the hierarchy) and this hierarchy has ramifications in terms of the properties; usually children inherit properties from the parents. The hierarchy in a MATLAB can be shown in Help of, "Organization of Graphics Objects." In this situation, it can be revealed that the organization involves.
In another word, the Figure Window involves Axes that are used to orient Core objects (primitives like rectangle, line, text) and Plot objects (that are used to produce area plots, bar charts, etc.).
We know that once an object handle has been stored in a variable, the function get can be used to find its properties, and set can be used to alter them.
