Create visualisation from script

[Håvard Fosså]

I borrow this thread.

I have used the code above with success, but i have a problem using additional icons.  When making a log out of my sample floor, i get this sub table for the param section:

"icons_add":[{"min":0,
"max":20,
"icon":"arrow-up.svg"},
{"min":20,
"max":80,
"icon":"minus.svg"},
{"min":80,
"max":100,
"icon":"arrow-down-active.svg"}],

How do i write the section for the additional icons?
