Lie Factor

Many problems can arise when fancy graphs are used over plain
ones. Distortions can occur when the heights of objects are used to indicate
the value because most people will pay attention to the areas of the objects
rather than their height. The lie factor is the ratio of the effect apparent
in the graph to actual effect in the data; if it deviates by more than 0.05
from 1, the graph is generally unacceptable. The lie factor in the following
graph is almost 6.
