Save animation as gif in GUI

Hello everyone!

I am trying to save an animation as .gif.

My plot is similar with given code below, I created with animated line too.

The problem is that, when I defined my figure as f=figure of figure(1) it creates .gif file properly.

However, instead of plotting my figure in separate screen using "figure" command, I have to plot in an axes on matlab gui axes as given figure.

I tried it with : " f=(handles.axes_threeDOF); ". But when I use this function,gif file creates different part of the screen. I attached that file too.

Could you help me to solve my problem?

Thanks in advance.

I want to create a gif of this animation:

But it creates as given below with this function " f=(handles.axes_threeDOF)"

numpoints = 500; 
x = linspace(0,4*pi,numpoints); 
y = square(x); 
y2 = 3 +square(x+1);
f = figure 
h = animatedline('Color','b','LineWidth',2); 
h2 = animatedline('Color','r','LineWidth',2);
grid on;
axis([0,12,-3,+6]) 
for k = 1:numpoints 
  addpoints(h,x(k),y(k)) 
  addpoints(h2,x(k),y2(k)) 
  drawnow  

  % Capture the plot as an image 
  frame = getframe(f); 
  im = frame2im(frame); 
  [imind,cm] = rgb2ind(im,256); 
  % Write to the GIF File 
  if k == 1 
      imwrite(imind,cm,'test.gif','gif', 'Loopcount',inf); 
  else 
      imwrite(imind,cm,'test.gif','gif','WriteMode','append'); 
  end 
end
