Script in Create Scripted Field form

[mrvincnezo (Ilia Katz)]

Thanks a lot @cjcenizal!

In was already familiar with that thread. After going over it again I found what I was looking for.

The script needs to go to the "Create Scripted Field" form, to the "Script" input

Then, in the Visualization, in the Advanced->Json Input one needs to specify {"script": {"lang":"groovy"}}.
