Gantt Chart

The earliest and best-known type of planning and control chart, designed to show graphically the relationship between planned performance and actual performance over time; named after its originator, Henry L. Gantt.

This type of chart is used for machine loading, where one horizontal line is used to represent capacity and another to represent load against that capacity, or for following job progress, where one horizontal line represents the production schedule and another parallel line represents the actual progress of the job against the schedule in time. Synonym: job progress chart.
