Find graphics objects with specified properties.
When called without arguments, return all graphic objects beginning with the root object (0) and including all of its descendants.
The simplest form for narrowing the results is
findobj (prop_name, prop_value)
which returns the handles of all objects which have a property named
prop_name that has the value prop_value. If multiple
property/value pairs are specified then only objects meeting all of the
conditions (equivalent to
-and) are returned.
The search can be limited to a particular set of objects and their descendants, by passing a handle or set of handles hlist as the first argument.
The depth of the object hierarchy to search can be limited with the
"-depth" argument. An example of searching through only three
generations of children is:
findobj (hlist, "-depth", 3, prop_name, prop_value)
Specifying a depth d of 0 limits the search to the set of objects
passed in hlist. A depth of 0 is also equivalent to the
"flat" argument. The default depth value is
includes all descendants.
A specified logical operator may be used between prop_name,
prop_value pairs. The supported logical operators are:
"-not". Example code
to locate all figure and axes objects is
findobj ("type", "figure", "-or", "type", "axes")
Objects may also be matched by comparing a regular expression to the
property values, where property values that match
regexp (prop_value, pattern) are returned.
Finally, objects which have a property name can be found with the
"-property" option. For example, code to locate objects with a
"meshstyle" property is
findobj ("-property", "meshstyle")
Implementation Note: The search only includes objects with visible
handles (HandleVisibility =
findall, to search for all objects including
Find graphics object, including hidden ones, with specified properties.
The return value h is a list of handles to the found graphic objects.
findall performs the same search as
findobj, but it
includes hidden objects (HandleVisibility =
"off"). For full
