% Serialize the data properties of a scattergroup so that data editing
% operations such as removing brushed data can be undone.

% Serialize a structure representing the graphic object data which is
% modified when taking action on brushed data. Some graphic
% objects, such as scatter, may need to add additional properties
% to this structure, e.g., SizeData and CData properties
