% CHANGELOG:
%
% * 11-1-2008:  Made sure that "XTickMode" is always set to "manual".
%
% * 14-1-2008:  If the difference between the max and the min of XTick is less than
%               6, then unit ticks are given.
%
% * 23-5-2008:  Updated the documentation.
%
% * 19-12-2008: Updated the documentation.
