How to export simulink graoh to MATLAB plot?

I have to create 2000 graphs using loops. Whenever I start running my code, it always shows the 1st iteration graph and saves it. The simulation is perfromed in simulink and I can see that the simulation is going accordingly but the main problem is on the figure saving. As I have said, it only saves the 1st figure. How can I sole this prolem?

It is rather difficult to understand your problem. Can you post a simplified version of your code to see what is going on?
