stem and leaf plot maps

http://libertisautoelectric.com/math-stem-and-leaf.html

Stem and leaf plot are designed to measure things up in numerical ways

index value plot maps

http://water.usgs.gov/waterwatch/regplots/

This is an index value plot of the streamflow in North Carolina. It shows whether the streamflow was above average (wet), average, or dry from 1999-2008.

Scatter plots allow you to visualize the variation in one variable relative to the variation in a second variable.

This is a scatter plot of North America

Box plot

http://www.nature.com/jcbfm/journal/v28/n4/full/9600584a.html

This map is able to help the reader by showing the average, or mean, which is the boxed area, but also gives the full range by presenting some of the outliers, through the extended lines.

Star plot

http://personal.cscs.ch/~mvalle/Libro/immagini.html

The above map is called a star plot and is a somewhat unknown but very useful tool in the world of mapping because it is able to take a characteristic that has many variables in it and display them at the same time so that the various types and varieties within a larger subgroup can be seen.

Accumulative line graph

Accumative line graph shows increase or decrease in values.

bilateral graph

bilateral graph depicts increases on one side of a zero line and a decreases on the other side.

Nominal area chrorpleth map

Nominal area choropleth map is a choropleth map that is used to dispaly nominal data.

Unstandardized choropleth maps utilize numbers when displayed.

This map shows Forage-Land use for all Hay and all Haylage, Grass Silage and Greenchop Harvested Acres, in 2002.

Standardized choropleth maps

This is a standardized map in cervical cancer showing the variations of it.

univariate chrorpleth maps

www.cdc.gov/pcd/issues/2007/oct/07_0091.htm
Univariate chrorpleth maps displays a single data set.

This map shows the percentage of individual in US.

Bivariate chrorpleth maps

http://proceedings.esri.com/library/userconf/proc99/proceed/papers/pap171/p171.htm

Bivariate mapping is an important mapping technique in cartography. Given a set of geographic features, it maps two variables on a single map by combining two different sets of graphic symbols.

Unclassed chrorpleth maps

http://www.esds.ac.uk/international/support/user_guides/gisoverview.asp

These maps shows difference between two different categories.

Showing different relations between two categories.

classified choropleth maps

http://curriculum.qcda.gov.uk/key-stages-3-and-4/assessment/nc-in-action/items/geography/9/1447.aspx

classifed choropleth map that uses graded differences in shading or color or the placing of symbols inside defined areas on the map in order to indicate the average values of some property or quantity in those areas

range greaded proportional circle map

http://pubs.usgs.gov/fs/fs-004-03/

A range graded proportional circle map is a proportional circle map that depicts the circles in relation to ranges of data. The information is classified as equal quantiles, breaks, natural breaks, and minimum variance.
