[Paraview] Chart View Question

[Brian Panneton]

So I have went with the filter and it seems to be what I need. However I
have run into an odd issue.

In my filter's xml, I have:

<Hints>
    <View type="XYChartView" />
    <Plotable />
 </Hints>

and the filter returns a table containing 4 columns as follows:
Node1: Data Received
Node2: Data Received
Time
vtkOriginalIndices

I was wondering how I can by default get Time and vtkOriginalIndices to not
show up.
If I have my filter go to a spreadsheet, then I open a Line Chart View and
show my data in it, I
end up with the line chart showing Node1: Data Received, Node2: Data
Received and a vertical line depicting which timestep we are currently on.

How can I have this show up by default?

Thanks,
Brian Panneton
