To create a line plot of the current field along the z axis, press the "Make a plot of the field along the Z axis" button. The field type for the plot will be the same as the displayed field type.

Re-sampling Volume Data to a Planar Uniform Rectilinear Grid

1. Load the mesh and mode as usual, making sure that "Read Internal Volume" is enabled.
2. Set up an appropriate mesh view.
   1. Hide the External Surface and show the Entire Volume (click the corresponding eye icons).
   2. Set External Surface drawing style to Surface if it isn't already (might default to Outline, which appears as a wireframe box)
   3. Set the surface to display a field you are interested in (so you can know that you will orient the sampling plane correctly)
   4. Select "Entire Volume" so that text is highlighted
3. Create the sampling filter
   1. create the filter: "Filters -> Alphabetical -> Plane Glyphs". This will show a wireframe bounding box and a red outline for the plane orientation.
   2. Position the plane where you want it. The most consistent and repeatable way to do this is to put values in for "Center" and "Normal" which specify a point in the plane and the plane's normal vector, respectively. Change "Resolution" to 100, and hit "Apply"
4. (Optionally) Save the data
   1. Presumably, this resampled data is to be exported, so make sure that only the resample filter is active and visible in the Pipeline Broweser, then
   2. "File -> Save Data", type in a file name, set "Files of Type" to be "CSV" (Comma Separated Values) which is readable by spreadsheets and matlab. Hit "OK".
   3. For "Configure Writer", you probably don't want to Write All Time Steps. And "Field Association" should be "Points". Hit "OK". (The file should be written to the same directory from which you originally ran ParaView, unless you navigated elsewhere.)

Uniform Grid of Cones

1. Create a Plane Glyph as described in "Re-sampling Volume Data to a Planar Uniform Rectilinear Grid", but skip the Save Data step
2. select the Plane Glyph in the Piepeline Browser
3. apply the Glyph filter
   1. "Filters -> Alphabetical -> Glyph" (or skip the menus and just hit the glyph icon)
   2. Set Vectors to the field you want to show (defaults to efield)
   3. Set "Gyph Type" to "Cone"
   4. Deselect "Masked Points"
   5. Accept other defaults. Hit the green "Apply" button. Note: cones will probably be the wrong scale at this point.
   6. Scale the cones by checking "Edit", and adjust the scale factor (usually down by an order of magnitude or so).
   7. Remember to hit "Apply" each time after adjusting the scale value.
   8. If, in the Pipeline Browser, the PlaneGlyphs was not automatically hidden when Glyphs was created, hide it.
4. Finishing touches
   1. The cones tend to look better when they are skinnier. Try setting radius to roughly 0.2
   2. If the visualization results are to be published or shown to others, the cones look much better at resolution 12 to 18 or so.
