ABSTRACT
The time honoured programming technique of bar charting is without doubt the best known means of illustrating projected production and providing a visual means of assessing actual output and progress. In recent years adaptations of bar charting, which indicate dependencies of one activity or part of the work upon another, have made the bar chart a powerful planning tool. Unfortunately, bar charting allows only limited amounts of information to be displayed, although the use of computers with their immense capability for data storage and retrieval allows the preparations of very meaningful charts for specific parts of the work.
