MATLAB: GUI position property issue…

gui position

Hello all! Well I'm attempting to change the position property of a GUI. I need to display different parts of a GUI at different times. So I have an example here showing two text boxes that show upper data and lower data, I need to resize the GUI to fit the lower data then fit the upper data. I know I can get the lower half easy, but the upper half is being a pain. Here is the example code:
    % Make figure 1
    f1 = figure('Name','Window 1');
    %Add some text boxes
    u1 = uicontrol(f1, ...
        'Style','text', ...
        'String','Upper Data', ...
        'Callback','feval(plotf)', ...
        'position', [250 380 100 15]);
    u1 = uicontrol(f1, ...
        'Style','text', ...
        'String','Lower Data', ...
        'Callback','feval(plotf)', ...
        'position', [250 20 100 15]);
    %grab current position data
    get(gcf,'position')
    %so you see both the upper and lower regions
    pause(2)
    %set new data
    set(gcf,'position', [677 610 560 210])
What I need is to find a way to get essentially a position of:
      set(gcf,'position', [677 610 560 210:420])
But that code is not the correct way to accomplish this. I need is a way to display the upper regions just like I display the lower regions.
Please help!
Thanks

as the position parameter starts with what i remember as the lower left corner you cannot just resize the figure to show the top portion. since if you resize it the bottom corner is locked to the bottom corner of the window. What you can do is shift the everything else!
      % Make figure 1
      f1 = figure('Name','Window 1');
   %grab/set current position data
      fposition = get(gcf,'position')
      yoffset = [0 fposition(4)/2 0 0];
      u1pos = [250 20 100 15];
      u2pos = [250 380 100 15];   
      %Add some text boxes
      u2 = uicontrol(f1, ...
          'Style','text', ...
          'String','Upper Data', ...
          'Callback','feval(plotf)', ...
          'position', u2pos);
      u1 = uicontrol(f1, ...
          'Style','text', ...
          'String','Lower Data', ...
          'Callback','feval(plotf)', ...
          'position', u1pos);
      %so you see both the upper and lower regions
      pause(2)
      %set new data
  %     set(gcf,'position', [677 610 560 210])
       set(gcf,'position',[fposition(1:3) fposition(4)/2])
% What I need is to find a way to get essentially a position of:
    pause(2)
      set(u1,'position',u1pos-yoffset);
      set(u2,'position',u2pos-yoffset);
