How to remove graph.

I've applied graph template to some devices (subdevices? whatever D ). Time passed, some things changed and I'm stuck with graphs that do not work at all (broken links to images) / work but I don't need them (I would like to remove them).

I hope it's silly question How to "unapply graph template"? )

Anybody?

If you're on a "view" page you can scroll to the bottom and click on the <edit> link. You can remove broken template graphs from there.
