[Paraview] PV 4.10 plot over line using mesh coordinates

[Cory Quammen]

Stephen,

Andy is right, that should work, but it isn't as straightforward as placing
two end points. Instead, you'll need to define the line as the intersection
of two planes, one of which is the plane used to extract the Slice and the
other is the plane from Plot on Intersections Curve. You'll need to
intersect these planes along the line you want to query.

HTH,
Cory
