Try typing "v" This should pop-up a panel that will let you select a
datum subset.
Hope this helps.

Hello,
Having looked at the docs and explored the UI, I can't tell whether
Paraview can do what I want. I have some scalar field data on a
regular grid. I import that into Paraview and then use the Gradient
filter to calculate the gradient of this data. Now what I want to do
is query both of these data sets and plot the scalar field data only
if it falls within a certain range of values AND its gradient also
falls within a certain range. I can imagine doing this either by
writing a filter to create a third data set which contains only those
points which pass the test, but neither the Calculator nor the Custom
Filter seem to let me do that. Or I could create the plot more
directly by creating a multivariate transfer function, but I can't
find any way to do that in the UI. Can Paraview do this kind of thing
from within the UI?
Eventually I will want to add the Laplacian and be able to query all 3
field properties in order to determine what to plot, but for now I
thought I would work on the simpler 2-variable case.
