Hello, I modified graph template and changed graph template items. Then, reinstated the template but my graphs is gone and the reason is that my all graph's data sources are empty. When i selected the right data source, it is OK, graph comes back. How can I restore all graphs

I would seriously consider moving to 1.2.22+. This can happen when you re-index the device, or you damage the template. This kind of thing does not happen in 1.2.22 these days, or very hard to break. You should manually be able to re-associate and hit save.
