Using slicer to display all values or none

[grimmg]

I need some help. I am trying to build some pivot charts in excel, the problem i am having is I have a dozen or more columns of data that I need to toggle on and off. I have my date as the row, and I have a dozen different variables for each date. I.E Nitrogen, Potassium Sulfur Ect. I would like to be able to toggle Nitrogen off for the entire period of time or sulfur, is this possible with a slicer

On the face of it if this is the type of thing you want to do then you probably want to unpivot your data using Power Query so that you have a column called e.g. "Elements" that you can slice by.
