1. A method for displaying a relational diagram on a display, at least one view of the relational diagram being larger than an available viewing area provided by the display, the method comprising:
- displaying a portion of a relational diagram in a display screen of a computer, a portion of the diagram extending beyond a display limit of the display so as to be unviewable in the display, but viewable by manipulating a scroll bar on the display;
detecting a predetermined action performed on a first element of the relational diagram in a viewable area of the display screen; and
,responding to the detection, byfirst determining one or more relevant elements associated with the first element that is not present in the viewing area but is present in the portion of the diagram extending beyond the display limit of the display,second determining a pre-set mode of view modification from amongst a selection of pre-set modes, the modes in the selection including pulling the one or more relevant elements from outside of the viewable area into the viewable area, moving a location of the viewable area to a location in which as many of the one or more relevant elements as possible are able to be displayed, with any remaining ones of the one or more relevant elements remaining outside of the viewable area pulled into the viewable area, centering a location of the viewable area on one of an originating one of the one or more relevant elements and a terminating one of the one or more relevant elements, with all other ones of the one or more relevant elements remaining outside of the viewable area pulled into the viewable area and moving a location of the viewable area to a location determined in accordance with a predetermined function, andmodifying a view of the relational diagram to display the first element and the one or more relevant elements not present in the viewing area within the viewable area of the display screen in accordance with the second determined pre-set mode.

1. A method for displaying a relational diagram on a display, at least one view of the relational diagram being larger than an available viewing area provided by the display, the method comprising:
-
displaying a portion of a relational diagram in a display screen of a computer, a portion of the diagram extending beyond a display limit of the display so as to be unviewable in the display, but viewable by manipulating a scroll bar on the display; detecting a predetermined action performed on a first element of the relational diagram in a viewable area of the display screen; and
,responding to the detection, by first determining one or more relevant elements associated with the first element that is not present in the viewing area but is present in the portion of the diagram extending beyond the display limit of the display, second determining a pre-set mode of view modification from amongst a selection of pre-set modes, the modes in the selection including pulling the one or more relevant elements from outside of the viewable area into the viewable area, moving a location of the viewable area to a location in which as many of the one or more relevant elements as possible are able to be displayed, with any remaining ones of the one or more relevant elements remaining outside of the viewable area pulled into the viewable area, centering a location of the viewable area on one of an originating one of the one or more relevant elements and a terminating one of the one or more relevant elements, with all other ones of the one or more relevant elements remaining outside of the viewable area pulled into the viewable area and moving a location of the viewable area to a location determined in accordance with a predetermined function, and modifying a view of the relational diagram to display the first element and the one or more relevant elements not present in the viewing area within the viewable area of the display screen in accordance with the second determined pre-set mode. - View Dependent Claims (2, 3, 4, 5, 6)

7. A system for displaying a relational diagram on a display, whereon at least one view of the relational diagram is larger than an available viewing area provided by the display, the system comprising:
-
a computer with memory and at least one processor and a display; and a display program comprising program instructions that execute in the memory of the computer in order to display a relational diagram on the display by displaying a portion of a relational diagram in the display of the computer, a portion of the diagram extending beyond a display limit of the display so as to be unviewable in the display, but viewable by manipulating a scroll bar on the display, detecting a predetermined action performed on a first element of the relational diagram in a viewable area of the display screen and responding to the detection by first determining one or more relevant elements associated with the first element that is not present in the viewing area but is present in the portion of the diagram extending beyond the display limit of the display, second determining a pre-set mode of view modification from amongst a selection of pre-set modes, the modes in the selection including pulling the one or more relevant elements from outside of the viewable area into the viewable area, moving a location of the viewable area to a location in which as many of the one or more relevant elements as possible are able to be displayed, with any remaining ones of the one or more relevant elements remaining outside of the viewable area pulled into the viewable area, centering a location of the viewable area on one of an originating one of the one or more relevant elements and a terminating one of the one or more relevant elements, with all other ones of the one or more relevant elements remaining outside of the viewable area pulled into the viewable area and moving a location of the viewable area to a location determined in accordance with a predetermined function and modifying a view of the relational diagram to display the first element and the one or more relevant elements within the viewable area of the display in accordance with the second determined pre-set mode. - View Dependent Claims (8, 9, 10, 11, 12)

13. A computer program product for displaying a relational diagram on a display, at least one view of the relational diagram being larger than an available viewing area provided by the display, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a device to cause the device to perform a method comprising:
-
displaying a portion of a relational diagram in a display screen of a computer, a portion of the diagram extending beyond a display limit of the display so as to be unviewable in the display, but viewable by manipulating a scroll bar on the display; detecting a predetermined action performed on a first element of the relational diagram in a viewable area of the display screen; and
,responding to the detection, by first determining one or more relevant elements associated with the first element that is not present in the viewing area but is present in the portion of the diagram extending beyond the display limit of the display, second determining a pre-set mode of view modification from amongst a selection of pre-set modes, the modes in the selection including pulling the one or more relevant elements from outside of the viewable area into the viewable area, moving a location of the viewable area to a location in which as many of the one or more relevant elements as possible are able to be displayed, with any remaining ones of the one or more relevant elements remaining outside of the viewable area pulled into the viewable area, centering a location of the viewable area on one of an originating one of the one or more relevant elements and a terminating one of the one or more relevant elements, with all other ones of the one or more relevant elements remaining outside of the viewable area pulled into the viewable area and moving a location of the viewable area to a location determined in accordance with a predetermined function, and modifying a view of the relational diagram to display the first element and the one or more relevant elements not present in the viewing are within the viewable area of the display screen in accordance with the second determined pre-set mode. - View Dependent Claims (14, 15, 16, 17, 18)
