Parallel coordinate plots are another way of looking a data. They enable researchers to view multiple variables simultaneously. There are two commands used to produce parallel coordinate plots,

parcoordandparcord2that we will be using. Here is how you can download the commands from ATS. You can download theparcoordcommand by typingsearch parcoordand you can downloadparcord2by typingsearch parcord2(see How can I use the search command to search for programs and get additional help? for more information about usingsearch). Now let’s take a look at several examples using thehsb2dataset.

parcoord read write math science socst

While this is kind of confusing, you can see that high scores on one variable do not necessarily guarantee high scores on all the other. Let's look at one variable,

read, but includefemaleandwrite.

parcoord female prog write

This is looking interesting but let's enhance the image by displaying males and females in different colors using the

parcord2command.

parcord2 female prog write, by(female)

Finally, let's try one more variation. Let's color the lines by

prog.
