[Paraview] min/max of coordinates

[Simone Crippa]

Hi,

someone have an idea how to extract the coordinate extrema of a dataset 
in PV? Suppose you extract with the threshold filter a certain volume 
cell region (unstructured), how can one then plot (e.g. over time) the 
minimum x-coordinate of the threshold?

The only hit on this in the PV mailing list is from the end of 2006, 
when Berk answered to a feature request for the calculator:

If someone has an idea on how to access this data (min/max), please tell 
me/us.

Maybe it is possible by using the python interface (PV3; programmable 
filter)? Any ideas?


Regards, Simone
