Bar chart hide data (not transparent)

I have the following data in a horizontal bar chart, Y-data: 1 column "name". X-data: 2 columns "Foo" and "Bar".  

Now within the bar-chart as such I have two legend items, "Foo" and "Bar". Within the bar chart I can click on "Foo" and "Bar" to hide either one of them. "Hide" in this is not litteraly hide, but it makes the proportion of the bar which is not selected in a lighter color (visually transparent). 

Now I would actually like that when either "Foo" or "Bar" are selected that they completly dissapear.

Is this possible to achieve? 

Via the "Foo", "Bar" it is possible to have them dissapear. However since the columns are numeric you have a numeric filter, where I would rather have that for the user it is simply a boolean button. Bookmarks wouldn't work since this is not the only data being used.
