Multimedia communication is influenced by increasing complexity and reach of information and by a rapidly growing user population. Due to these developments average authors of electronically published media have little expert knowledge in multimedia presentations. They are also confronted with considerable individual differences of recipients in culture, social life, education, psychology and physiology. In order to compensate for these shortcomings it is necessary to integrate interpretation and interaction abilities of individual users into future presentation and editing systems. We are developing a chart editing system which generates critics by user request. These critics are based on a user model, on expert knowledge in chart editing and on the currently edited chart. The system helps the author to avoid commonly made mistakes. It empowers recipients to adjust certain parameters (e.g.: colors) to their individual abilities and needs.
