<div dir="ltr"><div>Stephen,</div><div><br></div>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.<div><br></div><div>HTH,</div><div>Cory</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Jul 23, 2015 at 10:40 AM, Andy Bauer <span dir="ltr"><<a href="mailto:andy.bauer@kitware.com" target="_blank">andy.bauer@kitware.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">I think you may be able to get what you want if you first do a Slice through your domain (for 3D only) and then do a Plot on Intersections Curve.<br></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Jul 23, 2015 at 9:51 AM, Cory Quammen <span dir="ltr"><<a href="mailto:cory.quammen@kitware.com" target="_blank">cory.quammen@kitware.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi Stephen,<div><br></div><div>To my knowledge there is no filter in ParaView to do what you are asking. For an unstructured grid, it seems to me that no matter where the sample points are on the line, you are going to need some kind of interpolation at cell faces and edges where the line intersects the mesh structure to get the data values to plot. For structured grids, you might be able to plot values along a 1D subset of the mesh with some work, but not using the Plot Over Line filter.</div><div><br></div><div>Thanks,</div><div>Cory</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Jul 21, 2015 at 4:58 AM, Stephen Wornom <span dir="ltr"><<a href="mailto:stephen.wornom@inria.fr" target="_blank">stephen.wornom@inria.fr</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">One of the inputs to Plot over lineĀ is the number of points (equally spaced, I assumed).<br>
The solution is interpolated to the points. This poses a problem for highly stretched meshes like the normal coordinate in a boundary layer.<br>
<br>
I would like to plot over line using the actual mesh values and NOT the interpolated values.<br>
Is this possible in PV?<br>
<br>
How do I extract a line using the filters? That would be useful.<br>
<br>
Hope my questions are clear,<br>
