Separate updates on charts

I have two charts on 1 page. Ther are getting their values from 1 table. I do not want them to update when I choose some options from a slicer. I designed two slicers (one each) but again when I select from slice 1, it influence the chart 2. I do not want to have 2 tables with the same data to resolve this issue because then refreshment will be a hassle.

 I want to disconnect these 2 charts (not to be updated at the same time)
