Showing scriptnode peak graph on interface.

[lalalandsynth]

I can set the peak node to external display buffer but how can I show this peak graph on the interface ?
Its simple with tables , sliderpacks etc but I have no idea how to take a displaybuffer for something like that Peak node and show that graph.
I am trying to follow the Docs but it seems confusing to me as a shitty "programmer".

Any tips ?
