In perspective, in the desigenr when you click “+” next to pens, for example in the power chart component,

A new item is added in the array with an object structure with **default value**.

Is there a way to create a new item in pens array by script, but without specify all the props in order some props take default values ?

No, not in any dynamic way. That automatic behavior is a function of the JSON editor, not the actual property structure. You’d have to hardcode your ‘default’ elements for each possible value you would want to insert.

Maybe, but aren’t we all here because Ignition is a SCADA/HMI Utopia??!?  
Sorry @paul-griffith but I’m adding this to the wish list! maybe a system.perspective.addArrayElement is in our future…

I did hear they were working on adding custom ‘tooltips’ for properties. i suppose this is relativly similar as it also works with the json (atleast it does atm, no idea how they will implement it or when)
