Hi, I'm adding meta data to my vtkPolyData via vtkFieldData per http://www.itk.org/Wiki/VTK/Examples/Cxx/PolyData/FieldData. I see this metadata fine from the ParaView GUI but can't seem to do anything with the information without manually copying and pasting. Specifically I'd like to use some of the field values in a calculation via e.g. the calculator filter. Any way to do something like this?
