No, this is totally wrong. The graphs work with both the mutability and fa versions of dump1090.
There are two ways you can get Skyview map
(1) Uninstall dump1090-mutability and install dump1090-fa
OR
(2) Retain dump1090-mutability, and change only the GUI/Skin, so you see Skyview map instead of two-clock map.
For step-by-step instructions for both the above options, see thread [b]https://discussions.flightaware.com/t/tweaks/20339[/b], and go to "TWEAK #2: REPLACING TWO-CLOCK MAP BY SKYVIEW MAP (DUMP1090-FA)
