[Paraview] how can I produce a line plot from this quasi-1D structured mesh data?

[Noah Reddell]

I was able to get an adequate solution to work simply by applying the PlotOverLine tool.  The x-axis extents auto populated based on my structured 1D grid size.  I did have to set the Resolution property higher to capture all of my data.  In other words, the default resolution setting has nothing to do with the mesh resolution.
