View and set graphics object properties, define default values

You can control the behavior and appearance of a particular graphics object by setting its properties. To set properties, return the object as an output argument from the function that creates it. For example, the plot function returns a chart line object. Then, use dot notation to view and set properties.

p = plot(1:10,1:10); p.LineWidth = 3;

Alternatively, you can set properties using name-value pair arguments when creating the object, such asplot(1:10,1:10,'LineWidth',3). Most plotting functions support name-value pair arguments.

Topics

• Modify Graphics Objects
  This example shows how to create, display, and modify graphics objects in MATLAB®.
• Graphics Object Hierarchy
  Graphics objects are the visual components used by MATLAB® to display data graphically.
• Access Property Values
  You can set and query property values or return them to their original (factory default) values.
• Default Property Values
  Nearly all graphics object properties have predefined values, but you can define default property values.
• Multilevel Default Values
  This example sets default values on more than one level in the hierarchy.
• Default Values for Automatically Calculated Properties
  When you create a graph, MATLAB sets certain property values appropriately for the particular graph.
• How MATLAB Finds Default Values
  All graphics object properties have values built into MATLAB. You can also define your own default values.
• Factory-Defined Property Values
  Plotting functions use factory-defined property values if you do not specify values as arguments or as defaults.
