Hi all, I have a GUI which has a axes in it apart from other elements. The functions called in callbacks generate different figures, say 5 in number. I want to display them in the axes one by one,such that user can see the previous or next image by pushing two push buttons provided. What is the best way to do this. Thanks in advance.

    'Position',[10 20 60 40],...
    'callback',@newimg);
pbh1 = uicontrol(gcf,'Style','pushbutton','String','Previous',...
    'Position',[10 50 60 40],...
    'callback',@oldimg);
axes
text(0.2,0.5,'Press the buttons Next or Previous to see the images')

    function newimg(obj,event)
        showimg
        ImGN=ImGN+1;
        if ImGN>5

                  surfc(X,Y,Z)
              case 3
                  x = -2.9:0.2:2.9;
                  bar(x,exp(-x.*x),'r')
              case 4
                  x = -2.9:0.2:2.9;
                  plot(x,sin(x))
              case 5
                  t = 0:pi/50:10*pi;
                  plot3(sin(t),cos(t),t)
                  grid on
                  axis square
          end
