What is off the charts?

"Off the charts" is a phrase used to describe something that is beyond the range or scope of measurement or comparison. It may refer to data or results that are unusually high or low and cannot be graphed on a traditional chart. The phrase is commonly used in various contexts such as sports, economics, science, and politics to describe exceptional or unprecedented events or achievements. For example, a basketball player who scores more than 50 points in a game might be said to be "off the charts" or an economic growth rate that exceeds expectations could also be described as "off the charts."
