Complex data visualization method and equipment based on stacked tree graph

Abstract

The invention discloses a complex data visualization method based on stacked tree graph. For a complex data set to be displayed, the contained data is provided with time attributes and hierarchical relationship, and the visualization processing for the data set comprises the following steps: hierarchical processing to the date set can be performed according to self time attributes and hierarchical relationship of the contained data, so as to generate a tree shaped data structure; the generated tree shaped data structure is reflected to be a stacked tree graph on a two dimensional surface; and the stacked tree graph is drawn and displayed on a display plane. The invention further provides the complex data visualization equipment so as to meet the using requirements of the method. The invention solves the problems that a conventional time sequence visualization method cannot present hierarchy attribute and the hierarchical data visualization method cannot carry out visualization to data with time continuous attributes, thereby achieving the purpose of presenting hierarchical structure and time attributes of data within a limited space to a great extend.

Description

technical field [0001] The invention belongs to the field of information visualization, and in particular relates to a method and equipment for visualizing a large amount of complex data. Background technique [0002] With the development of information technology, the amount of information in various fields is also increasing rapidly. For a large amount of information data, how to obtain the valuable content hidden in the data is a concern of people. Visualization technology is to display all kinds of non-intuitive and abstract data with the help of computer graphics and other related technologies, so as to provide help for people to interact with data and obtain information contained in data. In China's authorized patent 200810108432.9, IBM proposed a method and device for visualizing a large amount of information. This method can map information such as a tree structure or data table containing a large number of data points onto a virtual spherical surface, and then proj...

Problems solved by technology

This system is a relatively mature application of hierarchical visualization methods, but there is also a problem, that is, the analysis of data that requires high timing, such as stocks. The change trend of the data cannot be displayed

In addition, although the hierarchical visualization technology can well see the comparison of the size of each sub-block from the graph, the user cannot intuitively obtain the specific value of a certain sub-block, let alone its proportion in the whole

[0004] Therefore, there is a common problem in the existing time series visual analysis methods, that is, the performance of the hierarchical structure of the data is poor, and the same hierarchical visualization method also has big problems in the performance of data quantification and development trends.
