What is off the charts meaning?

"Off the charts" is a common phrase used to describe something that is incredibly impressive or remarkable, to the point where it exceeds any known measurement scale or standard. It suggests that something has surpassed all expectations or predictions, achieving a level of success or excellence that is almost impossible to quantify. The origins of this phrase are likely to be related to the use of charts and graphs to represent data, where a value that is beyond the limits of the chart or graph would be considered to be "off the charts". It is often used in contexts such as sports, music, and business to describe exceptional performance, results, or achievements.
