Hi, I have a function(my_figure) that creates a figure by taking an array of variables(q) as argument and plotting according to the values of those variables.
my_figure(q)
I wish to animate a collection of such figures by varying the array of variables in a loop. I have come across 'refresh data' but cannot figure out how that is supposed to help me. Please help.

See getframe and movie functions in the MATLAB documentation.There is a following example:
Z = peaks;
figure('Renderer','zbuffer');
surf(Z);
axis tight;
set(gca,'NextPlot','replaceChildren');
for j = 1:20
surf(sin(2*pi*j/20)*Z,Z)
F(j) = getframe;
end
movie(F,20) % Play the movie twenty times

Thanks for your reply. It helps. But I seem to be getting an error that:
Error using hgMovie
Movie contains uninitialized frames
Error in movie (line 41)
builtin('hgMovie',varargin{:});
I can see that All the frames have been alloted a value. I cannot understand the reason for this error.
I have given a part of my code for reference.
figure;
a_plot_m(q_eq);
axis tight;
set(gca,'NextPlot','replaceChildren');
for j =1:10
qm=q2(:,j);
car_plot_m(q_eq)
F(j) = getframe(gcf);
end
movie(F,10) % Play the movie
