Point Data as Input to vtkOrderStatistics/vtkDescriptiveStatistics

I am trying to use the function vtkOrderStatistics in order to compute the 20% quantiles of the point-data in Sphere-Clips.
for example of this array: paraview.servermanager.Fetch(clip1).GetPointData().GetArray('activation bipolar (ms)')

How do I pass my point Data to the function?
As far as i found I could use SetInputArraytoProcess() or SetInputData()
SetInputData requires a vtkDataObject as Input.
So maybe i should print the Point-Values in a vtkTable and use that as Input?

How would that work? :see_no_evil:

It seems that you want to provide clipDataSet = paraview.servermanager.Fetch(clip1) as argument to SetInputData(clipDataSet) and provide activation bipolar (ms) for the SetInputArraytoProcess part.

Are you doing it like that because vtkOrderStatistics is not exposed in ParaView?

Is there another way to compute the 20% 40% 60% 80% quantiles in ParaView?
