I am needing to know if in the "Expression" language of Ignition, can you create variables that will only be use in that expression.

No.

The best thing to do to refactor a complicated expression is to introduce additional custom properties as intermediate steps, to simplify the final expression.

Thank you for the prompt response, now would you mind elaborating on how to use those custom properties or do you have an example I could look over to better understand what you are saying.

thanks.

What context are you authoring these expressions in? Vision, Perspective, somewhere else?
