A star plot is a way of displaying multivariate data in the form of a two-dimensional chart of three or more quantitative variables represented on axes starting from the same point. The relative position and angle of the axes is typically uninformative. The above star plot contains the star plots of 16 cars.

A correlation matrix is where all correlations are obtained from the same set of observations.

Similarity matrix

A similarity matrix is a matrix of scores which express the similarity between two data points. Higher scores are given to more-similar characters, and lower or negative scores for dissimilar characters.

Stem & Leaf

Stemplots retain the original data to at least two significant digits, and put the data in order.

A basic stemplot contains two columns separated by a vertical line. The left column contains the stems and the right column contains the leaves.

Box plot

Box plots are also known as box or whisker diagrams. They are useful in comparing multiple sets of data because they display the median, the average, and the level or measurement of dispersion.

Histogram

A histogram is a graphical display of tabulated frequencies, which are shown as bars. It shows what proportion of cases fall into each of several categories. The categories (bars) must be adjacent. The intervals are generally of the same size.

Parallel coordinate graph

A parallel coordinate graph is used to plot large multivariate sets of data. One line in a parallel coordinate graph connects a series of variable of different values.
