<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Here is a way of doing this. Apply a Programmable Filter with a script<br>
like this:<br>
<br>
displ = inputs[0].PointData['DISPL']<br>
val = numpy.sum(displ[:,0], 0)<br>
a = vtk.vtkFloatArray()<br>
a.SetName("Sumdispl")<br>
a.InsertNextValue(val)<br>
output.SetNumberOfRows(1)<br>
output.AddColumn(a)<br>
<br>
Make sure that the output type is set to vtkTable. Also, you need a<br>
ParaView compiled with Python and numpy support.<br>
<br>
Once you have the table, select the first row in the spreadsheet view.<br>
Then apply Plot Selection Over Time.<br>
<br>
This is a bit more complicated if the data is multi-block or AMR. Let<br>
me know if that is the case.<br>
