Abstract: Various technologies and techniques are disclosed that enhance chart customization. As one non-limiting example, a chart style reader reads the settings associated with available chart styles from one or more style files. A chart layout reader reads the settings associated with available chart layouts from one or more layout files. The chart style and layout files can be custom-defined by a user, and/or can be system-defined (built-in). Menu options can be displayed in the user interface to allow a user to select a particular chart style and/or layout. When the user selects a particular chart style and/or layout, the settings stored in the file are applied to a chart in the document by a chart object renderer.
