A Star Plot is a geographical method of displaying varying types of data in 2-D. They are represented on axes starting from the same point. It contains a sequence of equi-angular spokes called radii, with each spoke representing one of the variables. Star plots are helpful for small to moderate sized multivariate data sets.
A similarity matrix is a matrix of scores which express the similarity between two data points. They are used in sequence alignment: higher scores are given to more similar characters, and lower or negative scores are given for dissimilar characters.
Box plots can be drawn either horizontally or vertically.
A Histogram is a graphical display of tabulated frequencies, shown as bars. It shows what proportion of cases fall into each of several categories: it is a form of data binning. The categories are usually specified as non-overlapping intervals of some variable. The categories (bars) must be adjacent. The intervals (or bands, or bin) are generally of the same size.
