Saving Lots of Plots as Variable Changes in Time

Alright, this may be a simple question, but I am still learning. I am trying to generate a file with a variable number of plots, perhaps 10 per page. I have a variable, a, that I would like to change, and every time it changes I want a new plot. I was planning on doing this in a for loop like so:
for a=400:5:500
b(a)=equation
function
function
function
plot(output,'r');
axis([0 max(output)+10 -20 400])
hold on
plot(my data,'k'); %as background to see changes
hold off
end
Ideally, I would have 50 plots saved somewhere with all the different values of a worked through the functions. As it is, I get one plot with the final value of a input, which I expected due to the way I currently have it written.
I am also thinking it would be fun to make a movie showing the change in 'a' as it changes for each frame.
Any advice?

for a = 400:5:500
% do stuff to get your results.
figure(n)
plot(output,'r');
axis([0 max(output)+10 -20 400])
hold on
plot(my data,'k'); %as background to see changes
hold off
saveas(n,[folder '\' filename num2str(a) '.png'])
% eg saveas(n,['D:\My random storage location\' 'images' num2str(a) '.png'])
end
That'll save it all to file. (n can be any positive integer)
Look up the help documentation for "avifile" to get some of the code you need for creating avi files.

A lesson I learned from leaving a similar sort of program running overnight is to get rid of the figure once it's saved...
close(n)

And depending on what else you're doing/have done its best to make n an unusual number, like 171
