Handle Graphics

set(h,'Color','red')

You can also specify properties when you call the plotting function:

h = plot(x,y,'Color', 'red');

When y ou query the lineserie s properties,

get(h,'LineWid

th')

MATLAB returns t

he answer:

ans =

0.5000

Use the handle to see what properties a particular object contains:

get(h)

Graphics Objects

Graphics objects are the basic elements used to display graphs and user

interface components. These objects are organized into a hierarchy, as shown

by the following diagram.

Key Graphics Objects

When you call a function to create a graph, MATLAB creates a hierarchy of

graphics objects. For example, calling the

plot function creates the following

graphics objects:

• Lineseries plot objects — Represent the data passed to the

plot function.
