Abstract

A collection of data values is divided into plural bins, wherein a number of the bins is dependent upon a change feature of the data values. Parameter values associated with respective bins are determined. Based on the parameter values, visualization of the plural bins is provided in corresponding plural display screen partitions of a display screen, wherein at least one of the display screen partitions has a resolution that is different from another of the display screen partitions.

Claims

1. A method executed by a computer, comprising:

dividing a collection of data values into plural bins, wherein a number of the plural bins is dependent on a change feature of the data values;

determining parameter values associated with respective bins; and

based on the parameter values, providing visualization of the plural bins in corresponding plural display screen partitions of a display screen, wherein at least one of the display screen partitions has a resolution that is different from another of the display screen partitions.

2. The method of claim 1, wherein dividing the collection of data values comprises dividing a time series of data values into the plural bins.

3. The method of claim 1, wherein providing the visualization of the plural bins in corresponding plural display screen partitions comprises displaying a first one of the display screen partitions with a first matrix of display cells having a first size, and displaying a second one of the display screen partitions with a second matrix of display cells having a second size.

4. The method of claim 1, wherein providing the visualization of the plural bins in corresponding plural display screen partitions comprises displaying a first one of the display screen partitions that has a first size, and displaying a second one of the display screen partitions with a second matrix of display cells having a second size

5. The method of claim 1, wherein determining the parameter values associated with respective bins comprises determining the parameter values that indicate levels of interestingness of respective bins.

6. The method of claim 1, further comprising:

partitioning the collection of data values into plural segments;

assigning parameter values to the plural segments; and

forming the plural bins based on the plural segments, wherein at least one of the plural bins merges at least two adjacent segments.

7. The method of claim 6, wherein determining the parameter values associated with the respective bins comprises determining the parameter values associated with the respective segments, wherein the parameter value for the at least one bin is based on an average of the parameter values for the at least two merged adjacent segments.

8. The method of claim 1, further comprising:

computing indications representing resolutions of the display screen partitions based on the parameter values associated with the bins.

9. The method of claim 8, wherein computing the indications comprises computing fractions of an overall area of the display screen for respective display screen partitions.

10. The method of claim 9, wherein the parameter values make up a degree of interestingness profile, and wherein computing each of the fractions is based on a ratio of an area of the degree of interestingness profile corresponding to the respective bin, to the overall area of the degree of interestingness profile.

11. The method of claim 8, further comprising determining dimensions of each display screen partition based on the respective computed indication and number of data values in the respective bin.

12. The method of claim 1, wherein providing the visualization comprises displaying the display screen partitions as corresponding color-coded matrices.

13. The method of claim 12, wherein displaying the color-coded matrices comprises displaying data values of differing interestingness using different colors.

14. The method of claim 1, wherein the change feature comprises a change rate of the data values, and wherein dividing the collection of data values into plural bins comprises dividing the collection of data values into a larger number of bins in response to determining a higher change rate of the data values.

15. A method executed by program code embodied in a computer-usable storage medium, comprising:

assigning degree of interestingness (DOI) values to respective bins into which a time series of data values has been divided to indicate respective interestingness of the bins; and

providing a visualization of the data values in plural display screen partitions having dimensions based on corresponding DOI values.

16. The method of claim 15, further comprising computing the dimensions of the display screen partitions is based on the corresponding DOI values and number of data values in corresponding bins.

17. The method of claim 15, wherein each of the display screen partitions is a matrix of display cells, the method further comprising visualizing more interesting data values in display cells that are larger than display cells for visualizing less interesting data values.

18. The method of claim 15, wherein providing the visualization of the data values in the plural display screen partitions comprises displaying the plural bins of the data values using a multi-resolution display screen.

19. Instructions on a computer-usable storage medium that when executed cause a computer to:

divide a collection of data values into plural bins, wherein a number of the bins is dependent upon a change feature of the data values;

determine parameter values associated with respective bins; and

based on the parameter values, provide visualization of the plural bins in corresponding plural display screen partitions of a display screen, wherein at least one of the display screen partitions has a resolution that is different from another of the display screen partitions.

20. The instructions of claim 19, wherein the instructions when executed cause the computer to further:

compute fractions of an overall area of the display screen to be allocated to the display screen partitions, wherein the fractions are computed based on the parameter values associated with the bins.
