Thanks for your attention to my problem, I appreciate that; and the welcome 
. I actually don’t need to show/hide curves but rather recompute the curves as I edit parameters in the table (changing the period or amplitude). What would be the modification necessary for that?
(As a side note, if I run your example with pn.serve(...), it runs nicely (the selection hides/shows the curves) but not when I run it in jupyter lab, then the curves are not affected.)
