# To subscribers of the xforms list from "T.C. Zhao" <email@example.com> :
I think Steve mentioned that the xyplot only searches
for the first point that's within a given distance from
the mouse position, but sometime the point so found
may not be the closest. That might explain the problem
you're seeing. |In the latest code, I put extra code
to make sure the point returned is always the one that's
closes to the mouse.
