Box plot

"A boxplot, or box and whisker diagram, provides a simple graphical summary of a set of

data. It shows a measure of central location (the median), the average, and measures of dispersion. Boxplots are especially useful when comparing two or more sets of data."(Notes)

So in this data set, it shows the median score of each machine as well as each percentile. http://itl.nist.gov/div898/handbook/eda/section3/boxplot.htm

Histogram

A Histogram is a chart that displays a tabulated frequency. That means that it will show the number of times another data set was selected. So in the chart above, 6 scored a number of 50. http://www.netmba.com/statistics/histogram/

Parallel coordinate graph

Parallel coordinate graphs are made to show large amounts of information. They are not meant to indicate change as much as to get a lot of data into one graph. Each variable is graphed on a vertical axis. A data element is plotted as a connected set of points.  http://www.stat.columbia.edu/~cook/movabletype/archives/2007/10/parallel_coordi.html

Triangular plot

Triangular plots are designed to get the percents of sand, silt and clay out of a certain area. It tells the viewer what percent of each soil type makes up the other soil types. http://www.uwsp.edu/geo/faculty/ritter/glossary/s_u/soil_texture_triangle.html

Windrose

A Windrose map shows the direction the wind blew from most of the year. In this map the wind blew from the North less than 2% of the time. http://www.mathworks.com/matlabcentral/fileexchange/17748-windrose

Climograph

A climograph is a graphic representation of the relation between temperature and

precipitation as plotted at monthly intervals throughout the year. This graph above is showing that the rainfall is down and the temperature is up, causing the drought conditions. http://www.drought.unl.edu/whatis/climographs.htm

Population profile

Population profile or population pyramids as many people call them are graphs that display age and sex distributions for a given region. Depending on the shape of the graph, one can tell if the population is increasing, decreasing, or remaining constant. This map shows a large group of young people and a small group of elderly. http://www.scalloway.org.uk/popu4.htm
