% Function for replacing data in linked and unlinked graphics in linked and
% unlinked plots. Allows combined undo and redo operations when acting on
% multiple objects/variables. Functionality has been combined into a single
% function to avoid code duplication.

% Get the figure and the current parent object: axes if invoked from a
% context menu, otherwise figure

% Find replacement value/keep flag if none specified.  Use English for
% actionStr (it is only used for the undo/redo menu, and translation is
% performed when the undo/redo menu items are created)
