function has=hasbehavior(h,name,state)

%HASBEHAVIOR sets(enables/disables) or gets behaviors of hg objects

%

% HASBEHAVIOR(H,NAME,STATE) sets the behavior named NAME for the 

% hg object with handle H to STATE (true or false). The NAME

% is case-insensitive. The name 'legend' is used by the LEGEND

% command to enable or disable showing the object in a legend.

% HAS = HASBEHAVIOR(H,NAME) returns the boolean value for the

% behavior NAME of H.  If the behavior has not been previously 

% set for H, then 'on' is returned. 

%

%   Examples:

%       ax=axes;

%       l=plot(rand(3,3));

%       hasbehavior(l(1),'legend',false); % line will not be in legend

%       hasbehavior(l(2),'legend',true); % line will be in legend

%

%       linelegendable = hasbehavior(l(1),'legend'); % gets legend behavior
