[Paraview] 2d data visualization

[John Doe]

Thanks for the suggestion.  My vector data is defined on lines, not
points.  The glyph filter does not appear allow me to select any of
this data.  Is there any way to make the data selectable, or do I
somehow have to interpolate the celldata onto points?

Thanks,
Juan
