Parallel Coordinates Plot
Here we plot the variable values for some set of cases.
You may either show parallel coordinates for each case, or you
may choose to show the traces only for the identified cases.
In that case, the cases corresponding to "sticky" labels are
drawn with thinner lines.
The case profile is drawn using the color and glyph of the point
identified in the main plotting window.
Display
You can choose independently whether to have the points
and the lines drawn in the case profile window.
Link
You may unlink it from identification in the plotting window --
if you're looking at all profiles and you have many points, you
might want to do this, because it can get quite slow ....
Y Scale Style
Either plot all variables using a common vertical axis, or
use each variable's own axis.
Include Missings
Display missings or leave them out. This can provide an
interesting view of the distribution of the missing values.
