Definition
A Hockey Stick Chart is a type of line graph that exhibits a long period of relative stability or low variables, followed by an abrupt and significant upward trajectory. The chart’s shape resembles a hockey stick, where the blade represents the stable period, and the handle illustrates the sudden spike. This chart is particularly useful for showcasing explosive growth rates in various fields, including business revenue, scientific research, and economic statistics.
