Visualization system including data navigator for use with digital computer system

The invention relates generally to the field of digital computer systems, and more particularly provides a system and arrangement for facilitating the visualization of data generated by a digital computer system during the processing of a program. The invention is useful in connection with, for example, a debugger program to verify correct operation of another program being debugged with use of the debugger program, as it provides a mechanism for viewing at least a portion of data, either scalar data or data in the form of multidimensional arrays, generated during processing of the program being debugged, and also provides a mechanism for easily navigating through the arrays to facilitate viewing of data from diverse regions of the arrays. A data visualization arrangement for facilitating the display of data items comprising a selected region of an object in a selected one of a plurality of display modes. The arrangement comprises a data object store, an interface, an object region retrieval component and a display. The data object store stores the data object, the data object comprising a plurality of data items in a predetermined organization. The interface receives a region identification for identifying a particular region of the object and a display mode identification. The object region retrieval component retrieves data items from a region of the data object as identified by the region identification received by the interface. Finally, the display receives the data items as retrieved by the object region retrieval mechanism and displays them in the display mode as identified by the display mode identification.
