For your second question, maybe you could do something with this resource:

If you want your chart config to persist per user across sessions and logins, you'll have to save that config somehow. This resource lets you save trend configs to a database and load them up again. If you modify it a little, you might be able to automatically save the current config on a view's _onShutdown_ and automatically load it on the chart's _onStartup_ etc.
