Edit data cursor with several points

Does anyone know how to edit the data cursor to fulfil the function in which we can click the mouse in several times and record the all 3D coordinates(such as click mouse three times, generate three group datas) into Excel file without enter "Alt"? I can only record one 3D coordinate right now, the code as follow:

function output_txt = myfunction(obj,event_obj)
% Display the position of the data cursor
% obj          Currently not used (empty)
% event_obj    Handle to event object
% output_txt   Data cursor text string (string or cell array of strings).
pos = get(event_obj,'Position');
output_txt = {['X: ',num2str(pos(1),4)],['Y: ',num2str(pos(2),4)]};
% If there is a Z-coordinate in the position, display it as well
if length(pos) > 2
    output_txt{end+1} = ['Z: ',num2str(pos(3),4)];
end
xlswrite('1.xls',output_txt);

The data cursor doesn't seem to me to be the right tool for this job. I think you want ginput instead.

Thanks! I know ginput could be used in 2D pictures, but it doesn't seem to work well in 3D?
