Star Plot


A star plot allows for the comparison of multiple variables of different types of data. For example, here the model is comparing 1-9 different types of data of 16 different cars. Note the similarities between the Buick Electra and the Cadillac DeVille.

Stem and Leaf Plot


These types of plots are a valuable way to show small amounts of information.

Box Plot


"Box Plot representation of distances covered by First Division Brazilian soccer players (n = 55) according to playing positions after 90 minutes of play, including only those who played the whole game. The players were classified in five positional groups: central defenders (CD, n = 15), external defenders (ED, n = 12), central midfield players (CM, n = 11), external midfield players (EM, n = 9) and forwards (F, n = 8)."

This type of data representation is good in understanding groups of numerical data. It looks like the Central Defender came in first.

Histogram of Precipitation


This histogram was compared with another in order to understand reflectivity rates for a dual polarization radar. It's all very complicated actually.

Parallel Coordinate Graph

This type of graph plots points lying on a common line or plane create readily perceived structures in the image.
