Re: Interactive Scatter Plots...

After reflecting on Barry's question, I have added a method:

  public int getCloseIndex()

to PickManipulationRendererJ3D.java.  If the picked Data
object is a Field, calling this method on the
PickManipulationRendererJ3D that links the Field to the
DisplayImpl will return the index of the picked sample
in the Field.  This will allow applications to avoid having
a large number of Data objects in the display, one for each
point, in order to know which point is selected.

Cheers,
Bill
