The above image is a triangular plot of three dietary specializations on what animals actually eat (fruits and seed, animal matter, and leaves, flowers, gum and sap). An animal has been plotted within the triangle according to its diet. A triangle plot is also known as ternary plot and graphed with 3 different vaiables.

The above image is an image of a wind rose. A wind rose is a graphic tool used by meterologist to give them a view of the wind speed and direction. The length of each spoke around the circle is related to the frequency that the wind is blowing.

Climograph

The above image is a climograph from Walgett, Austrailia. A climograph shows the monthly precipitation and temperature conditions for a selected place (in this case it would be Austrailia). Percipitation is shown by a bar graph and temperature is the line graph.

Population Profile

The above image is a population profile for Mobile County. The age is on the y-axis and the x-axis are the percentages of each age class to the total population divided up into two columns (males and females). There is a smaller percentage of 20 - 30 year olds with a slight increase in the 40 year old range representing migration and the baby boom. A population profile shows the age and sex distributions for any given region.

Scatter Plot

The above image is a scatter plot showing the wife age as a function of the husband age or paired ages. As you can see in the plot above there is a strong relationship between the husband's age and the wife's age...meaning the older the husband the older the wife and vice versa. A scatter plot is a graph of two or more variables that are plotted on the Y-Axis and X-Axis to show their relationship with each other.

Index Value Plot

The above image is an index value plot for the United States showing the current water resource conditions recorded in January 2001. The information is calculated each day as an average of the streamflow index values for all the stream gaging stations located in the state or water resource region that have at least 30 years of recordings.

The above image is a lorenz curve showing the income of the people in Scotland. The chart shows a slight increase in equality from 2000/01 to 2005/06. The yellow line shows perfect equality and the red and dashed lines are the lorenz curve that shows the actual income. A lorenz curve is a graph that shows the concentration of ownership of wealth and income.
