A box plot is a simple way of graphically depicting numerical data.  It is done through five-number summaries: sample min, Q1, Q2, Q3, and sample max.

Parallel Coordinate Graph

A parallel coordinate graph shows multiple sets of data or information, which is plotted on the vertical axis. Each line represents a different set of data and is a different color.  Parallel coordinate graphs are good for comparing larger amounts of data in one graph.
