That is so simple, and I hadn't thought of it at all. Thank you! My only
concerns would be for slowness of plotting if there are a lot of points and
just code simplicity, and so if there could be some other way with a custom
function for the picker that would do this, I would probably prefer that.
But maybe neither of these are particularly important concerns.
