Embodiment 1

[0052] The embodiment of the present invention provides a graphical representation method of a compact hierarchical data structure, see Figure 4 , the method includes the following steps:

[0053] 101: Each data set constructs a corresponding tree data structure according to the internal hierarchical relationship;

[0054]102: Each node corresponds to a node block in the graphical representation, and each node block has key attributes of grade, height, length, starting position, color, shading, simple text information and detailed text information;

[0055] Through the above settings, the user can quickly locate the position of each node in the tree structure and obtain some key information of the node. In specific implementation, it can also include other key attributes, which can be set according to the needs of practical applications. The present invention The embodiment does not limit this.

[0056] 103: Quickly judge the importance of the node block through the length ...

Embodiment 2

[0062] The scheme in embodiment 1 is further introduced below in conjunction with specific calculation formulas and accompanying drawings, see the following description for details:

[0063] For convenience, the figure 1 The tree structure in is taken as an example for description, and the graphical expression method proposed in the embodiment of the present invention is called a block tree. Figure 5 given in figure 1 The block tree representation corresponding to the tree structure given in . The block tree can be placed according to the needs such as "from left to right", "right to left", "top to bottom" and "bottom to top" (during specific implementation, the embodiment of the present invention does not do this limit). The following is a detailed description of its production method in a "top-to-bottom" manner.

[0064] 201: Construct a corresponding tree data structure for the data set according to the internal hierarchical relationship;

[0065] For the convenience ...

Embodiment 3

[0106] Below in conjunction with two examples, accompanying drawing, the scheme in embodiment 1 and 2 is carried out feasibility verification, see the following description for details:

[0107] 1. Use the block tree to realize the visual expression of the discussion post data:

[0108] In the information society, in many cases, different people will participate in the discussion of the same issue. For example: every discussion post in the forum. Usually, a discussion post is initiated by one person who proposes a topic for discussion. In the follow-up, different people will reply to this topic according to their own interests.

[0109] Figure 8 It is a simple discussion post structure. exist Figure 8 , the text in the text box is the opinion expressed by the user. The letters in the first gray box behind indicate the user who posted this opinion, and the numbers in the second gray box indicate the order in which these opinions were published. In this example, user A ...

Abstract

The invention discloses a graphic expression method and apparatus for a compact hierarchical data structure, which is a lineless hierarchical structure data graphic method and apparatus. The method comprises the steps that data sets construct a tree data structure according to internal hierarchical relations; each node corresponds to a rectangle called as a node block in graphic expression, and each node block has level, height, starting position, length, color, shade, simple text information and detailed text information attributes; according to the attributes or artificially defined lengths of leaf node blocks and the lengths of sub-node blocks, the length of a father node block is determined; according to the starting position of the father node block, the starting positions of the sub-node blocks are determined; and the sub-node blocks are arranged on the lower side (the upper side, the left side or the right side) of the father node block to represent a subordination relationship. According to the method and the apparatus, hierarchical data is subjected to graphic expression compactly and clearly, so that the space is saved, the working efficiency is improved, and the needs in actual application are met.

Description

technical field [0001] The present invention relates to the field of information visualization, in particular to a graphical representation method of a compact hierarchical data structure. The method visualizes the tree structure, and can visualize hierarchical data such as file systems in computers and discussion posts in forums. Expressed vividly. Background technique [0002] At present, there are many hierarchical data in the information field that can be expressed as a tree data structure. There are many ways to visualize tree structures. The following are several graphical representation methods of the tree structure: [0003] Example 1: A tree is a common data structure, figure 1 It is a graphical expression method of tree structure. It clearly defines the master-slave relationship of different nodes, which can make people understand the hierarchical relationship of the entire tree structure. But when the tree contains more data, such as figure 2 shown. Repres...
