Help : Independent visuals selections based on buttons

Hi ,
Requirement : **When I select a button only the specific visual has to change (this one I can do with bookmarks)**
I have 2 visual independently (and 2 on exactly on top of them)
I have four buttons , 2 on top of each visual
button1chart button2table
-------chart visual----
-------table visual---------
--------------------------
button3chart button4table
-----chart visual-----------------
------table visual----------------------
---------------------------
Now when I select button2table , the chart visual should change to table
After this when I select button4table , the chart visual should change to table (the first visual table should remain table)
After this , when I select button3chart , the visual should come back to chart (but still the first visual should remain as table).

It's like the visual should change independently.
how can I achieve this ?
please help
Note : I have tried bookmarks and selection panes
But the problem is when I bookmark button4table , I don't know the above visual is in which state and that state should not change

Thank you Much Appreciated
