Return a selected column name from graph builder

[#1]

Is there a way to return the selected column from the column list in graph builder when you run a script?  For example, if I were to have selected age in the column list:

and then run a script, would I be able to get the age column name and use it?  The reason I ask is that I have "shortcut" scripts that help with data clean up.  I often see issue in graph builder and then run a script that asks me to select the column I want to modify, however this is actually redundant as I had already selected the column in graph builder.  So if I could have the script grab the name of the selected column in the graph builder column list I could avoid some extra input boxes and clicks.

Thanks for any ideas!

This JSL will return the value selected in a Graph Builder dialog box

variable = Current Report()[listboxbox( 1 )] << get selected;

Perfect!  Thanks so much for a quick reply.

Have a good day!

Playing around with this, I am now wondering is there something similar for the column switcher box?

1. The same JSL will work if a Column Switcher is invoked.  It will return the selection from the Column Switcher.
2. Do you understand what the line of JSL is doing?  
3. I suggest that you read the documentation in the Scripting Guide, on Display Trees.

Thanks for the additional info and no I don’t understand it yet but plan on getting there. I’ll review the info you suggested. Thanks again.

To @txnelson's point, the documentation and the Scripting Index will inform you that the Column Switcher is an object with its own protocol, including the message << Get Current specifically for your need.
