Why x, y-ticks are not shown in avi animation? Animation is made using VideoWriter(), getframe, writeVideo() functions.

      turn=0;
      v=VideoWriter('test.avi');
      open(v);
      set(gca,'nextplot','replacechildren');
      N=20;
      xx(1:N)=0;
      plot( (1:N),'o-' );grid on;ylim([-1.5,1.5]);
      title(sprintf('turn %d',turn));
      xlabel('address');
      ylabel('amplitude');
      axis tight manual
    for turn=1:100
        xx=sin(2*pi*(1:N)*0.1+2*pi*turn*0.01);
        plot( (1:N),xx,'o-' );grid on;ylim([-1.5,1.5]);
        title(sprintf('turn %d',turn));
        legend( sprintf('turn:%d',turn) );
        xlabel('address');
        ylabel('amplitude');
        frame=getframe;
        writeVideo(v,frame);
    end
    close(v);
