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

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.
