Tracking a joint distribution over time (scatter plot)

Last Updated: Sept 12, 2012

Challenge: Visualize how the distribution of two different measurements on a set of samples (fish, people, countries) changes over time, and which observations exceed some critical value on one or both measurements.

Solution: show joint distribution and individual distributions side by side (rather than stretched in the margins); mark critical range by changing point symbols; show change over time by scrolling through pages, like an old flipbook
