A METHOD OF GRAPHICALLY REPRESENTING A TREE STRUCTURE

摘要

In a data visualization system, a method of creating a visual representation of data points from metric data, wherein the method includes the steps of: a data retrieval module retrieving the metric data from a data storage module in communication with the data visualization system, a determination module determining the data points based on the retrieved metric data, and a display module arranging the data points for displaying on a display device according to a predetermined visual representation, arranging the data points into a plurality of meta groups in a hierarchical manner, and arranging the meta groups into a plurality of layers, where each layer represents the data points at different levels of granularity, and a statistical distance determination module determining a statistical distance between items in the meta groups, and the display module arranging the items within the meta groups based on the determined statistical distance.
