How to use datacursormode to collect multiple points without using keyboard

Excuse me if i am posting this at the wrong place. If this is the case, please refer me to the right place.

Problem: Using datacursormode to collect multiple points without using keyboard.(Matalb 2013b)

.

Solution: (This example taken from a code built for guide, hence the handles....)

r=datacursormode(get(handles.axes2,'Parent'));
set(r,'DisplayStyle','window');
info=getCursorInfo(r);
while  (isempty(info) == 1)
    info=getCursorInfo(r);
    pause(0.1);
end
points3D=info.Position;
datacursormode off;   % delete getcursorinfo(r); => makes info empty
datacursormode on;

The time on pause can be changed, but I found 0.1 gives you a repsose quick enough to click the points quickly without dropping.
