Embodiment Construction

[0057] Further illustrate the present invention below in conjunction with accompanying drawing.

[0058] The technical solution of the present invention is divided into three steps: the first step is to determine the calculation method of the force between the node pairs in the graph; the second step is to determine the mapping relationship between the node attribute value and the force in the graph layout based on the node attribute transfer function; The third step is to design different transfer functions according to different attribute categories.

[0059] Specific steps are as follows:

[0060] 1. Determine the calculation of the forces between pairs of nodes.

[0061] The graph layout method based on transfer function is an improvement on the traditional force-directed layout algorithm. The traditional force-directed layout algorithm adopts the spring model, and the vertices are regarded as points with mass, and there are mutually repulsive forces between vertices. T...

Abstract

A map layout method based on node attribute transfer functions comprises the following steps: 1, calculating the acting force between a pair of nodes; 2, mapping the attribute values of nodes to parameters related to force in map layout; 3, designing different transfer functions according to different attribute categories; 4, constructing the map layout based on the node attribute transfer functions according to the results of the step 3.

Description

technical field [0001] The invention relates to a graphic display method of network data. Background technique [0002] Network data refers to data that can be expressed as a graph structure, which exists widely in social media, financial transactions, biological networks and other fields. With the rapid development of Internet technology, these network data are increasing. In order to better understand these data and obtain valuable information from them, it is necessary to have appropriate methods to study these data. As an important means of information processing, network visualization technology has always been the focus of people's research. It makes full use of the human visual perception system to display network data in the form of graphs, and quickly and intuitively explain and overview network structure data. Network visualization mainly uses a graph layout method based on node connection graphs to display the relationship between data. Through an effective gra...
