Add a switch for the controls in the statistics graph card

[tweimann]

I suggest to add a switch for the controls in the Statistics Graph Card.

How it should be with the switch turned off:

Why? Because when I add like 5 Graphs and have every option enabled half of the card are just these buttons that I don’t really need. Thanks

Note: you will still be able to view which sensor is which by hovering over the line

Option to hide "min/max" legends in the statistics graph

I really like the statistics graph but I think the color scheme makes it clear what’s the mean, the min and the max so I would love to have an option to continue to display the 3 graphs but not their legends.
