Parrallel Coordinate Graph

A parallel coordinate graph makes is easier for one to see differences in multidimensional data. The example above shows several factors at the same time; the percentage of a baseball measure, for nine players, over four different levels (as shown on the horizontal axis).

Stem and Leaf Plot

Stem and leaf plots show a frequency showing which classes of values occur. It is used widely in statistics and can help one to see a shape in the distribution of the numbers. It is similar to a histogram, but it shows more. The example above shows the frequency of infant mortality rates in Africa.

Box Plot

The above is a simple example of a box plot, also know as a box and whisker plot.  This type of graph shows the median, upper and lower quartiles, and minimum and maximum values of a set of data in a simple display.

Histogram

A histogram is a visual representation of data in order to see how the data is distributed. It is close to a bar graph, but shows data in frequency form. The data is separated into categories, labeled, and graphed. The above is showing the frequency of a behavior pertaining to a simulation.

Triangular Plot

A triangular, or ternary plot, is used to plot and compare three variables dependent of eachother.  The above triangular plot shows the relative abundance of Methylhopane in a given rock sample.

Windrose

This unique graph is used to display how wind direction and speed are distributed in a particular area.  This specific windrose shows a distribution of wind direction.

Climograph

A climograph shows weather for a particular area over a period of time, usually a year. It is widely used by scientists to show temperature and precipitation on the same graph, such as the one above showing a city in Colorado's weather for a given year.
