Index Value Plot

Index Value Plot- a graph that shows the index value for each point, which is the ratio of the value to the total of all the values, instead of a concrete number.

This index value plot shows the shift in ocean temperatures from 1900-2008. Orange values are above average temperatures, and blue values are lower than average temperatures. The article with this graph argues that changes in ocean temperatures are common and long-lasting, and that a rising ocean temperature is not necessarily related to intense climate change.
