Providing an ellipsoid having a characteristic based on local correlation of attributes

摘要

Data records are grouped into clusters according to attributes of the data records to be correlated. At least two of the clusters that satisfy a proximity criterion are merged. At least one ellipsoid is created for presentation in a scatter plot visualization based on the grouping and merging, the ellipsoid including pixels representing multiple corresponding data records. The ellipsoid has a characteristic based on a corresponding local correlation of the attributes of the data records represented by the ellipsoid. The characteristic of the ellipsoid is adjusted based on a direction of the local correlation.

1. A method comprising:
grouping, by a system having a processor, data records into clusters according to attributes of the data records, the attributes to be correlated; merging, by the system, at least two clusters that satisfy a proximity criterion; creating, by the system, at least one ellipsoid for presentation in a scatter plot visualization based on the grouping and merging, the ellipsoid including pixels representing multiple corresponding data records, wherein the ellipsoid has a rotation angle that is based on a corresponding local correlation of the attributes of the data records represented by the ellipsoid; and adjusting the rotation angle of the ellipsoid based on whether the local correlation is a positive correlation or a negative correlation, wherein a first rotation angle of the ellipsoid corresponding to the positive correlation results in a dimension of the ellipsoid having a positive slope, and wherein a second rotation angle of the ellipsoid corresponding to the negative correlation results in a dimension of the ellipsoid having a negative slope.
