How do i zoom into a specific XY location?

I have loaded an image into axes and created a contextmenu (right-click menu). When I right click my mouse the menu appears with zoom options such as zoom in and zoom out.

GOAL: When I right click and click "Zoom In" I want to zoom into the location where I right clicked.

EX: zoom(factor, x, y)

MY CODE:

% --------------------------------------------------------------------
function importImage_Callback(hObject, eventdata, handles)
% hObject    handle to importImage (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

%global im im2

filename = uigetfile({'*.jpg;*.jpeg;*.tif;*.png;*.gif','All Image Files';});
global im im2
im = imread(filename);
im = im2double(im); %Conver to double
im2 = im; %backup process

imshow(im,'Parent', handles.axes1)
image(im,'hittest','off')

function digitize_Callback(hObject, ~, handles)
% hObject    handle to digitize (see GCBO)

ng=0;
nXY = [];
n=0;

[writefname, writepname] = uiputfile('*.txt','Save data as');
writepfname = fullfile(writepname, writefname);
fid = fopen(writepfname,'wt');

      while 1
            [x,y, buttonNumber] = ginput(1);
        if buttonNumber == 1, 
           line(x,y,'Marker','.','Color','r','MarkerSize',12)
             sn = num2str(n + 1);
             text(x,y, sn)
             n = n+1;
           disp(sprintf(' %4d         %f      %f',n, x, y))
           ng = ng+1;
           nXY(ng,:) = [n x y];
             fprintf(fid,'%g,%g,%g\n',n, x, y);
        elseif buttonNumber ~= 3
           query = questdlg('STOP digitizing and QUIT ?', ...
          'DIGITIZE: confirmation', ...
          'YES', 'NO', 'NO');
           drawnow
           switch upper(query),
          case 'YES',
         disp(sprintf('\n'))
               break;
              %case 'No',

         end % switch query
      end
  end

    fclose(fid);
