[Paraview] Support for text visualization in Paraview

[M. Nawijn]

Hello,

To support correlation between physical test data and simulation data,
I import both test data (strain gauge measurement data) and simulation
data (finite element structural analysis data) into Paraview.
Currently we face the challenge that we need to keep track of
approximately 700 strain gauge locations and corresponding values. I
represent these strain gauges as 1D cells (Vertex) in Paraview. Each
of the vertices is than colored by the strain value. This allows very
nice comparison of test and simulation during a test. Since we
reference these strain gauges with unique string labels it would be
very nice if it would be possible to visualize these labels in
paraview. A possibility would be to have a cell or point label. I have
two questions:
   1. Is this already possible with paraview (and how to do it)
   2. If not can someone estimate how much effort it would take to
implement it (if all possible). I would be happy to share the code if
anyone is interested.

Kind regards,

Marco
