A representation of numbers signifying different data sets. Graphs are vitally important in tracking past performance of economic data with the aim of predicting its future behavior. For example, a government agency may create a graph of unemployment claims over time. If claims have trended downward, the agency may predict that unemployment may remain low. Graphs are also crucial for technical analysts, who use them to track securities' performance to help make investment decisions. Graphs are also known as charts.
Data displayed in a diagrammatic manner, often to show relationships between different sets of numbers. Charts are used to observe the historical values of variables and, frequently, to spot trends that may provide insights for use in projecting future values. Also called graph.
