[Paraview] Connecting points with line

[Andy Bauer]

Hi Patrik,

You need to specify what columns in your table from your csv file
correspond to the point coordinates for your points. If you look at the
information tab you should be able to see how many points have been created
by the Table to Points filter.

Regards,
Andy
