CL_g_tag

Description

• Puts a tag on graphic entities (i.e. sets the "user_data" property) if that entity has not already been tagged (that is if the user_data value is []).

  This function may be used in conjunction with CL_g_select to change some graphic properties without having to go through the graphic hierarchy (which avoids dealing with expressions like a.children(1).children...).

Parameters

root:

Root of the hierarchy of graphic entities to be examined. Default = current axes (gca()).

tag:

(optional) Value to be used to tag the graphic entities. The value can be any value (and of any type) except '*'. Default is [] (user_data value not changed).

h:

Vector of the graphic entities that have been tagged.
