Monitor
When working on subsets of a data set parallel coordinate plots can help to relate
features of a specific subset to the rest of the data set. For instance, when looking
at the result of a multidimensional scaling procedure, parallel coordinate plots
can help to find the major axes, which influence the configuration of the MDS.
Figure

shows a
-D MDS along with the corresponding parallel coordinate
plot. Querying the letmost cases in the MDS shows that these cars are all hy-
brid cars with very high gas mileage. he top right cases in the MDS correspond
to heavy cars like pickups and SUVs. Obviously, similar results could have been
found with biplots.
