Abstract

Methods, systems and recordable media for viewing large data sets having extremely disproportional dimensions on a symmetrical display. Data sets in matrix form having many more rows than columns or vice versa may be manipulated to make maximum use of a symmetrical display. Further data management processes facilitate navigation through large datasets and provide the ability to look at one or more portions of the data set in detail while still maintaining the context of the entire data set, or a larger portion of the dataset.

Claims

1. A method of manipulating large datasets for display, wherein a first dimension of the data to be displayed is much larger than a second dimension of the data to be displayed causing the dataset to be disproportional to a display on which the dataset is to be viewed, said method comprising the steps of:

subdividing the dataset along the first dimension to form segments of the dataset, each segment having a fraction of the first dimension and all of the second dimension; and

displaying at least a subset of the segments adjacent one another on the display, thereby using the area of the display more efficiently.

2. The method of claim 1, wherein all of the segments are displayed on the display at the same time.

3. The method of claim 1, wherein said subdividing is performed automatically, based on the first and second dimensions and dimensions of the display on which the dataset is to be viewed.

4. The method of claim 1, wherein at least one of a number of said segments formed by said subdividing and a size of at least one of said segments is determined by user input.

5. The method of claim 1, wherein said segments have approximately equal dimensions.

6. The method of claim 1, further comprising the steps of:

selecting a location on one of the displayed segments;

displaying a line through the center of the location and parallel to the first dimension to establish a reference line relative to the second dimension; and

displaying a line on each of the remaining displayed segments, parallel to the first dimension and at the same location relative to the second dimension established with the generation of the line through the center of the selected location.

7. The method of claim 6, further comprising selecting another location on one of the displayed segments, and repeating the displaying steps of claim 6 to display reference lines with regard to more than one selected location.

8. The method of claim 1, further comprising the steps of:

providing means for user selection of a location to establish a reference line relative to the second dimension;

inputting a location to establish the reference line; and

displaying a line through the location and parallel to the first dimension to establish a reference line relative to the second dimension at the inputted location, on all displayed segments.

9. The method of claim 8, further comprising dragging and dropping one of the displayed reference lines to change the location thereof relative to the second dimension, wherein the remaining reference lines corresponding to the reference line having been dragged and dropped are automatically repositioned to the same respective location relative to the second dimension.

10. The method of claim 6, further comprising dragging and dropping one of the displayed lines to change the location thereof relative to the second dimension, wherein the remaining lines corresponding to the line having been dragged and dropped are automatically repositioned to the same respective location relative to the second dimension.

11. The method of claim 1, further comprising the steps of:

selecting an area within one of the displayed segments to be zoomed;

zooming the selected area to be zoomed, in the second dimension, so that only the selected portion of the segment in the second dimension is displayed while the entire first dimension of the segment is displayed; and

zooming corresponding areas of the remaining displayed segment in the second dimension, so that only the dimension of the corresponding area in each segment is displayed while the entire first dimension of each segment is displayed.

12. The method of claim 1, wherein only a portion of the total number of segments are displayed on the screen at any one time, said method further comprising:

providing means for scrolling from one screen of displayed segments to another; and

scrolling from the displayed screen of segments to another display of other segment not displayed on the displayed screen of segments which was scrolled from.

13. The method of claim 1, further comprising selecting less than all of the segments that are displayed;

zooming the selected segments to maximize use of the display; and

displaying only the zoomed, selected segments.

14. The method of claim 1, further comprising selecting less than all of the segments that are displayed, subdividing the selected segments, zooming the subdivided, selected segments and displaying the subdivided selected segments.

15. The method of claim 14, wherein a number of subdivided, selected segments is equal to a number of segments that were previously displayed prior to said selecting less than all of the segments.

16. The method of claim 1, wherein a number of said segments formed by said subdividing is selected by user input, and further wherein a selected portion of the dataset along the second dimension is displayed based upon user input.

17. The method of claim 16, further comprising calculating a centroid of data values within the selected portion along the second dimension, and displaying a centroid line through the calculated centroid value on the display.

18. The method of claim 16, wherein the dataset is a subset of a larger dataset selected through user input.

19. A method comprising forwarding a result obtained from the method of claim 1 to a remote location.

20. A method comprising transmitting data representing a result obtained from the method of claim 1 to a remote location.

21. A method comprising receiving a result obtained from a method of claim 1 from a remote location.

22. A system for manipulating large datasets for display, wherein a first dimension of the data to be displayed is much larger than a second dimension of the data to be displayed causing the dataset to be disproportional to a display on which the dataset is to be viewed, said system comprising:

a display;

means for subdividing the dataset along the first dimension to form segments of the dataset, each segment having a fraction of the first dimension and all of the second dimension; and

means for displaying at least a subset of the segments adjacent one another on said display, thereby using the area of the display more efficiently.

23. A computer readable medium carrying one or more sequences of instructions for manipulating large datasets for display, wherein a first dimension of the data to be displayed is much larger than a second dimension of the data to be displayed causing the dataset to be disproportional to a display on which the dataset is to be viewed, wherein execution of one or more sequences of instructions by one or more processors causes the one or more processors to perform the steps of:

subdividing the dataset along the first dimension to form segments of the dataset, each segment having a fraction of the first dimension and all of the second dimension; and

displaying at least a subset of the segments adjacent one another on the display, thereby using the area of the display more efficiently.
