You can see the legend on the right hand side is showing every instance of the same type. Is there a away that it can only show one instance of each and toggle all types of that type. i.e. it would only show Cheese, Bread, Jam
Clicking cheese would unselect Cheese in both groups.

I also cannot find a way to display any way of differentiating the two groups

Is there a way to add a label to show this? (Like I have drawn one and two on the series)
