Placement of cells in bins to provide non-overlapping visualization of data points of a scatter plot

摘要

To provide non-overlapping visualization of data points of a scatter plot, bins in a visualization screen are defined. The bins are defined along a first dimension by a first attribute of the data points, and along a second dimension by a second attribute of the data points. Cells representing corresponding data points in the bins are placed using a placement algorithm that positions the cells in the bins according to values of the first and second attributes of the corresponding data points. If the placement algorithm detects plural data points that have identical values of the first and second attributes, the placement algorithm groups the data points having the identical values in nearby positions surrounding a position corresponding to the identical values of the first and second attributes to avoid overlay of the data points having the identical values of the first and second attributes.

1. A method executed by a computer of non-overlapping visualization of data points of a scatter plot, comprising:
defining bins in a visualization screen, wherein the bins are defined along a first dimension by a first attribute of the data points, and along a second dimension by a second attribute of the data points; and placing cells representing corresponding data points in the bins using a placement algorithm that positions the cells in the bins according to values of the first and second attributes of the corresponding data points, wherein if the placement algorithm detects plural data points that have identical values of the first and second attributes, the placement algorithm groups the data points having the identical values in nearby positions surrounding a position corresponding to the identical values of the first and second attributes to avoid overlay of the data points having the identical values of the first and second attributes.
