Slicer for multiple graphs

I have 2 line graphs. The graph A has 3 lines, Voltage (R), Voltage (S) and Voltage (T). The graph B has 3 lines, Current (R), Current (S), Current (T).

How do I create a slicer to slice these 2 line graphs with 3 lines each, such that the slicer has 3 options R,S,T.

And when I select R in the slicer, graph A would show Voltage (R), and graph 2 shows Current (R)?
