Hiding Legend Items in Graph Builder using JSL

[#1]

I am having an annoying issue with the Graph Builder in JSL.  In order to show both the points and a smoother on a scatter plot I am changing the trasnparency of the points.  I can make this work well enough but when I manipulate the plot later in JSL the points are being added back to the legend by default instead of staying hidden I assume because JMP thinks they are no longer redundant.  I know manually in the graph builder you can uncheck items that you don't want to display but is there a way to do this in JSL?

Thanks @txnelson and @jjswan33 for your answers!

I need to slightly adapt it to make it match with my script but I think I will work.

Thanks again :)

And thank you @anne_sa.  Your info pointed me in the right direction.
