extract to array plotDataOverTime

ParaView Support

Hello,
I have a filter (plotDataOverTime), and i would like to recover its value to an array. eg., avg(alpha.air). i can see the values in a spreadsheet viewer if i am in row data. what i would like is to get an array where each value corresponds to a timestep (ie., a value of a line of the data i see for plotDataOverTime in the spreadsheet).
generally I do something like this:

filter= GetActiveSource()
data=dsa.WrapDataObject(servermanager.Fetch(filter))
fieldWanted=data.PointData['fieldWanted'].tolist().copy()

but there is no Point/CellData here.
PS. is there any documentation specifically for fetching etc data? I would like to get an answer but furthemore read more about this, each time i want to do something like this is a hit or miss situation…

PS2. the plotDataOverTime is used over a integrateVariables filter (in case that it is helpfull)
thanks

Does the following code work as expected?

from paraview import servermanager
from paraview.vtk.numpy_interface import dataset_adapter as dsa

filter= GetActiveSource()
table = dsa.WrapDataObject(servermanager.Fetch(filter).GetBlock(0))
fieldWanted = table.RowData['fieldWanted'].tolist().copy()
