Abstract:

GGobi is a descendant of XGobi, with many additions and improvements, including multiple plotting windows, flexible color management, XML file handling, and portability to Windows.

GGobi has been designed so that it can be extended in two ways. First, it can be embedded in other software and controlled using an API (application programming interface), and one of its embedding environments is R. Second, it can be extended using plug-ins. The plug-ins can be used to handle different data formats, and to add algorithms, graphical user interface controls, or plot types, and they can be written in C, Java, or the S language.

When GGobi's plug-in mechanism is used with R, specialized graphical displays can be designed that include R graphics alongside GGobi plotting windows, and those displays can be linked so that they update together.
