% GraphicsPlaceholder Default graphics object.
%
% The graphics.GraphicsPlaceholder class defines the default graphics
% object. Instances of this class appear as:
%
% * Elements of pre-allocated arrays created with hobjects.
% * Unassigned array element placeholders
% * Graphics object properties that hold object handles, but are set
% to empty values
% * Empty values returned by functions that return object handles (for
% example, findobj).
%
% Usage:
% graphics.GraphicsPlaceholder() - Creates a GraphicsPlaceholder.
%
% Example:
% x = linspace(0,20,101);
% y = sin(x);
% %
% hPlot = plot(x,y);
% hCBar(3) = cursorbar(hPlot);
% hGPHolder = hCBar(1)
%
% GraphicsPlaceholder Constructor:
% GraphicsPlaceholder - GraphicsPlaceholder constructor.
