[Paraview] interactively plotting points in 2D ImageData

[Randy Heiland]

Utkarsh,  Thanks for the prompt reply!  That does indeed work - as far as plotting the values.  But what about showing the associated horiz line across the imagedata?  And what about being able to interactively/dynamically translate that line up/down?  Are there options other than changing the Y range of the VOI for the ExtractSubset filter?  Is it possible to at least lockstep the Y's min/max?
