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? 🙈

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?
