[Paraview] Write xml for ParaView Plugin

[Tuan Ha Tran]

Hi Seb, 
   Thank you for your reply.
   I'm sorry that I don't quite understand your instructions. I'm really new to ParaView.
   With my little knowledge in ParaView, I'll try to understand as follow : 
   - First, I have to write my .xml file with a tab that have "function" declaration? So how to declare these values cause I don't understand the exemples in the *.xml file (filters, writers; etc.)
   - And then by the declaration as your instructions about information_only yesterday?
 
   Can you be a little more explicit? What is ROI?
   
   Thank you very much for your kindness.

You should do that in two step.

On property on your proxy where you set the ROI.
And one information property where you calculate...
