[Paraview] Chart View Question

[Utkarsh Ayachit]

Brian,

The Extension mechanism for adding representation types in only
supported by the SurfaceRepresentation and other representations in
the 3D view. We haven't really provided any support for adding
different representation types if Chart views. For your use-case, I
think the easier option would be to create a filter that extracts the
block of interest from the multiblock dataset that contains the
vtkTable and then directly show that in the chart view. The user will
have to explicitly apply this filter. Alternatively, your source can
have two output port, one producing the data to be shown in the 3D
view and the other a vtkTable that can be directly shown in the chart
views.

Does that help?

My reader's output would be in the form of a vtkMultiBlockDataSet which would hold information for both representations (polydatas for representation 1 and vtktables for representation 2) The same vtkMultiBlockDataSet would be passed to each representation where the representation would control what would be sent to the view. For 1, the tables would be ignored and for 2, the polydatas would be ignored.
