I have tried via the Python interface. This works fine for me:

px = servermanager.ProxyManager()

view = servermanager.GetRenderView()

label = servermanager.sources.TextSource()

# here you must get the right data. I assumed "reader" was the source of
your data

label.Text = "# of cells: %d" %
reader.GetDataInformation().GetNumberOfCells()

labelRep = servermanager.filters.TextSourceRepresentation(Input=label)

view.Representations.append(labelRep)
view.StillRender()


getting the right handle on your dataset is left as an exercise, since
it is application dependent
