Bar chart is the most common graph when we need to process some data counting, analysis and comparing. But there is no inner bar chart object in IDL object graphics. According to the outlook demands and the functional requirements of bar char object, a visual expression method of bar char object was implemented based on the inner basic graphics objects in IDL. The implementation method was presented in detail. The results show it can meet the requirements of bar char displaying of common information, and it is effective and extendable.
