You have two choices: register different templates for each graph and invoke new file for each of them.
The drawback is you will have document object created for each template.

If you are using the same data to display different graph, you can use template to create initial frame/view/doc and create frames for all other views using the same document instance.
I did it for my database managing my project, to display different views for database.

If you need sample, let me know.
