My question is :
Why are graphics Pression and Température displayed in both Overview and Graphiques tab ?
If I add a ‘view: yes’ tag in group meteo, a new tab is created and group ‘meteo’ disappear from Overview… But the same config doesn’t seems to work with graphics…
I actually think that group meteo disappearing from overview is unintended. In my experience, the overview tab always has everything unless you turn it off. I could be remembering incorrectly though because I turn off everything except for a few items in my overview page.
You are probably encountering a bug with the history_graph component. Personally, I do what @g0g0 said and only display the information I want on my default page. It cleans things up and can be used as a summery page. The downside is that you need to comment out the default_view: override when adding new devices to verify they work before placing them in the correct spot in your interface.
