[Paraview] Using field data as text source?

[Mark S. Bentley]

Hi all,

I've been using ParaView to view discrete element model data, imported 
as a time series of legacy VTK files. I've just added field data to the 
output data so that I have per-timestep global data (e.g. thermal energy 
of the system, number of particles etc.). This loads into ParaView fine 
alongside by particle data.

Now I would like to write this out to the screen as text during 
animations, but can't figure out a way to do it - can the text source 
not use a Field Data variable as its source? Is there something I'm 
missing, or should I hit python?

Regards,

Mark
