GUI_28()
function [] = GUI_28()
% Demonstrate uicontextmenu for an axes click.
% Clicking on the axes plots a single point.  After plotting as many points
% as desired, the user may click in the axes to access two options
% concerning the plotted points.
%
% Suggested exercise:  Add another menu to the context menu which
% exports the current plot into another figure then clears the GUI axes for
% more playtime.
