Wow, Curtis, that's exactly the behavior I am looking for. I'll take a
little while to digest the code, but it looks very straight forward.
(I'm especially pleased that I can use Gridded2DSets).
Any idea whether this is more efficient than mulitple D_R_M's?
Thanks again!!

Hi Kevin,
I've considered two other ways to approach this:
1) Create an array of DataReferenceImpl's that do pretty much the
same thing (redraw the radial when moved - like the AnchoredPoint
method) and space them so that the user should (almost) always have
one visible no matter how they manipulate (pan/zoom) the display.
2) Somehow change the endpoint location of the DataReferenceImpl to
always be in the viewable area. The difficult part of this is to
move the DataReferenceImpl down the existing radial (along and toward
the origin).
Another option is to do manual picking. It takes more code than a
direct manipulation renderer, but you have more control. (And in your
case, it may be less code than dealing with N direct manipulation
renderers distributed along the line.) I have posted an example called
RadialLine.java on my VisAD examples page at
http://www.ssec.wisc.edu/~curtis/examples/ that demonstrates this. It
allows you to pick anywhere along the radial line using the right
mouse button as you describe.
