[Dune] Questions on GnuplotWriter

[Alexander Schlaich]

Hi Christian,

I didn't visualize it in 3d.
In fact I can look at planes of my solution or project to a plane, but 
the solution is like expected from analytical expression as well as the 
vertex points.

It's just that in my simple case the data format is appropriate and 
therefore in my opinion brings less overhead than using vtk. Maybe the 
name GnuplotWriter is confusing for this particular application ;-)

Alex
