Right. As I mentioned in my email from last night, I suspected the
problem was with the PlotOverLine object, and I was right. I wasn't
defining that properly, so the CSV file was empty.
Attached is the working file.
Thanks again,
Steve

You can use the following:

w.UpdatePipeline()
When all is working well, would you share your python script?
Thanks in advance,

Hi all,
I am using Paraview 3.7.0 to view a large number of data files, each
with
the same geometry. I need to load the geometry and volume data, use
PlotOverLine to extract the magnitude of a variable along a
particular line,
and then save this data to a CSV file.
Due to the large number of data sets I am dealing with, I have been
trying
to use the Python Trace functionality to automate this, and I am
able to do
everything except for saving the CSV file at the end. I have
browsed around
quite a bit over the past few days, and I understand that the trace
functionality does not work for save data commands, but I was
wondering if
someone could help me find the Python object that contains the
relevant data
so that I can write my own little routine to dump it to a CSV file.
Many thanks for any help you can offer.
Steve
