[Paraview] Paraview programmatically plot quantities over line, using only data on nodes

[Utkarsh Ayachit]

I'd suggest trying the nightly binaries (or wait for 5.5 release
candidates which should come out in the next week or so). A new **Plot
Data Over Time** filer will let you do this without have to worry
about selecting cells/points etc.
