CxxNonOverlappingAMRExample: What is the writer for PlotOverLine filter

#1

Hi,

Using Examples/Catalyst/CxxNonOverlappingAMRExample as prototype, I want to replace Slice with PlotOverLine:

  p = PlotOverLine(Source='High Resolution Line Source')
  p.Source.Point1 = [-10.0, -10.0, -10.0]
  p.Source.Point2 = [10.0, 10.0, 10.0]
  # create a new 'Parallel MultiBlock Writer'

What writer should I use? XMLMultiBlockDataWriter does not work:

( 0.869s) [pvbatch ]vtkDemandDrivenPipeline:813 ERR| vtkPVCompositeDataPipeline (0x3ca2b90): Input for connection index 0 on input port index 0 for algorithm vtkXMLPMultiBlockDataWriter(0x3ca0970) is of type vtkPolyData, but a vtkMultiBlockDataSet is required.

Also, I would like to save a png image, and data as csv. What are the correct writers for this?

Thanks,
Ted
