[vtkusers] [Paraview] node/element tracking

[Sebastien Jourdain]

Hi Ben

Here is the steps to achieve exactly what you want.

On your data, make a selection of the points you are interested in.
Then apply the filter "Plot Selection Over Time"
This will draw a chart for you. But once you have that new data in the
pipeline browser, you can view it also in a spreadsheet view ( split +
create spreadsheet view), or you can export that data to a CSV file
for further processing.
