[Paraview] please help do constuct 3d surface chart from csv file

[Chris Botha]

I am a new user to Paraview - and therefore do not know what to do
when you say to apply the transform filter. I therefore searched the
web for more information on how to apply the transform filter in
Paraview. The best I could find was here :
http://www.paraview.org/pipermail/paraview/2009-March/011560.html  - I
was able to use that answer to apply the scale that I need.

I have also applied the Delaunay filter - and now have a 3d surface
chart that I wanted!

What do I need to do to see the coordinates of the cursor as I move it
over the surface chart? I need to see the values of the local maximum.

Regards

Chris
