Mac – Activity Monitor dock icon CPU history aggregate

activity-monitormac

On my old Mac I have a CPU history icon showing single aggregate graph.

enter image description here

On the new Mac running the same OS version and having the same number of cores I can't seem to find this option. History only shows individual CPUs.
In my size of icons it's not very useful.

I wonder if there's an internal unofficial setting to display CPU history icon as a single aggregate graph (like on the first image).

Just a one-liner of ATrubka's solution for ones wondering how to edit the plist file:

defaults write com.apple.ActivityMonitor DisplayType 0
