How to load json into array

Hi, I would like to have an array with 4 sets of points (x,y).

Looks like I need to create an array in the files folder, then open the array editor -

then I need to load the array editor data into the array object that is created in the layout. Is this documented somewhere?

I don't get how to load the points data into the array object.

Thx much

Add the AJAX plugin to your project. To load the array file use the following sequence of actions:

AJAX:Request yourArray.json

System: Wait for previous actions to complete

yourArrayObject: Load from JSON string AJAX.lastdata

thanks for that!
