Abstract

Provided are, among other things, systems, methods and techniques for displaying data by accessing a set of data records that have associated indexes and generating pixels to represent the data records, the colors of the pixels being based on attribute values of the data records. The pixels are arranged into lines based on the associated indexes, with each line corresponding to a segment of indexes and adjacent lines corresponding to adjacent segments, and the arranged pixels are displayed.

Claims

1. A method of displaying data, comprising:

accessing, by a computer, a set of data records that have associated time indexes;

generating, by the computer, pixels to represent the data records, the colors of the pixels being based on attribute values of the data records;

arranging, by the computer, the pixels into plural bars that represent first time intervals;

segmenting, by the computer, each of the bars into bar segments that represent second time intervals;

arranging, by the computer, the pixels into lines within each of the bar segments based on the associated time indexes, with each line corresponding to a third time interval and adjacent lines corresponding to adjacent third time intervals, wherein the first, second, and third time intervals are different time intervals;

displaying the pixels as arranged in the bars, bar segments, and lines of pixels;

inserting visible gaps between bar segments in each of the bars; and

in each of the lines, providing filler pixels to represent missing data records to cause lengths of the lines to be equal, wherein each of the filler pixels has a predefined color that is different from colors assigned to pixels associated with the data records in the set.

2. A method according to claim 1, wherein the bar segments are defined by a specified dividing attribute of the data records, and wherein the pixels are arranged within each of the bar segments based on a specified ordering attribute.

3. A method according to claim 1, wherein the pixels are arranged chronologically within each of the lines.

4. A method according to claim 1, wherein each line corresponds to a uniform time interval, wherein the third time interval is the uniform time interval.

5. A method according to claim 1, wherein each pixel represents exactly one data record instead of aggregations of data records, the method further comprising:

organizing the pixels within each of the bar segments according to values of an ordering attribute of the data records.

6. A method according to claim 1, further comprising obtaining display information from a user, and wherein the pixels are arranged in the bars, bar segments, and lines in accordance with the display information.

7. A method according to claim 1, wherein the lines have different numbers of pixels, with a number of pixels in each line depending upon a number of data records within the third time interval corresponding to the line.

8. A method according to claim 1, wherein the pixels are displayed on a dynamic display device, and wherein contents of a desired data record automatically are displayed upon designating a corresponding one of the pixels.

9. A method according to claim 8, wherein said designating comprises dragging a cursor over said one of the pixels.

10. A method of displaying data, comprising:

accessing, by a computer, a set of data records that have associated time indexes;

generating, by the computer, pixels to represent the data records, the colors of the pixels being based on values of a coloring attribute of the data records;

arranging, by the computer, the pixels into bars of parallel lines, based on the associated time indexes;

segmenting each of the bars into bar segments, wherein the lines represent respective first time intervals, the bar segments represent respective second time intervals, and the bars represent respective third time intervals, and wherein the first, second, and third time intervals are different time intervals;

displaying the pixels as arranged in the bars, bar segments, and lines of pixels,

wherein each pixel corresponds to a different single data record, and each of the pixels has a maximum dimension of less than 5 millimeters;

receiving user input to indicate whether filler pixels are to be used;

in response to receiving user input indicating that filler pixels are to be used, providing filler pixels in each of the lines to represent missing data records to cause lengths of the lines to be equal, wherein each of the filler pixels has a predefined color that is different from colors assigned to pixels associated with the data records in the set; and

in response to receiving user input indicating that filler pixels are not to be used, displaying the lines of pixels without filler pixels for the missing data records.

11. A method according to claim 10, wherein each of the parallel lines corresponds to a uniform time interval, the first time interval being the uniform time interval.

12. A method according to claim 10, wherein the pixels are displayed on a dynamic display device, and wherein contents of a desired data record automatically are displayed upon designating a corresponding one of the pixels.

13. A method according to claim 10, wherein each of the pixels corresponds to respective single data records rather than aggregations of data records.

14. A computer-readable medium storing computer-executable instructions for

displaying data, said instructions upon execution causing a computer to:

access a set of data records that have associated time indexes;

generate pixels to represent the data records, the colors of the pixels being based on values of the data records;

arrange the pixels into plural bars that represent first time intervals;

segment each of the bars into bar segments that represent second time intervals;

arrange the pixels into lines based on the associated time indexes, with each line corresponding to a third time interval and adjacent lines corresponding to adjacent third time intervals, wherein the first, second, and third time intervals are different time intervals;

display the pixels as arranged in the bars, bar segments, and lines of pixels;

in each of the lines, provide filler pixels to represent missing data records to cause lengths of the lines to be equal, wherein each of the filler pixels has a predefined color that is different from colors assigned to pixels associated with the data records in the set.

15. A computer-readable medium according to claim 14, wherein each pixel represents exactly one data record, the instructions upon execution causing the computer to further:

organize the pixels within each of the bar segments according to values of an ordering attribute of the data records.

16. A computer-readable medium according to claim 14, wherein the instructions upon execution cause the computer to further:

insert visible gaps between bar segments in each of the bars.

17. The computer-readable medium according to claim 14, wherein each of the pixels represents exactly one data record instead of aggregations of data records, the instructions upon execution causing the computer to further:

organize the pixels within each of the bar segments according to values of an ordering attribute of the data records.
