Plotting a Shaded region using the movie function

I am using the Movie function to save a gif, everything I tried disappears when I open the gif.

I am trying to create a region where is x-axis < 1/2(x) - 5 and less then 1/2(x) + 5. basically between 1/2(x) - 5 < x < 1/2(x) + 5 and up and down y axis.

    % Plot
    pause(.1);
    plot(Ey, 'r-', 'LineWidth',2);
    hold on
    plot(Hx, 'g-', 'LineWidth',2);
    legend('E_y Field', 'H_x Field');
    axis([0 z -2 2])
    hold off
    M(:,t) = getframe ;

Use xlim() to set the field of view along the x direction, then save the movie or gif as you're doing now.

Attached are a variety of movie demos. See the one called movie_made_from_surf.m, which is kind of like yours.
