handles.dcm_obj = datacursormode(hObject);
set(handles.dcm_obj,'Enable','on','UpdateFcn',{@myupdatefcn,hObject});
In the myupdatefcn callback, you will need to define the text string (similar to the output you have shown in the image). As this uses pos, then you have access to the third element which you can set back in the edit text field of your GUI since we are assuming that the hObject passed into this callback (when set above) is the handle to the figure.
function txt = myupdatefcn(~,event_obj,hFigure)
pos = get(event_obj,'Position');
txt = 'something using pos';
handles = guidata(hFigure);
if isfield(handles,'text1')
set(handles.text1,'String',num2str(pos(3)));
end
The above assumes that text1 is the control to update with your text.
