Problems solved by technology

[0040] The disadvantages of the image layout method used in step 4 of this method are: ① when there are many nodes in the graph, there will be many cross lines (points) in the graph; ② the image layout method does not take into account other nodes connected to a certain node. The layout of multiple nodes in geometric space causes the distribution of these nodes in the graph to be scattered
The above problems will result in poor readability of the hierarchical system structure diagram automatically generated by the system, which is not conducive to intuitively reflecting the hierarchical structure of the system

Abstract

The invention discloses a graphic layout method applicable to a software visualization process, which belongs to the technical field of software visualization. The method comprises: firstly, setting the left upper corner of canvas as the origin of coordinate, performing deep search of a to-be-processed digraph obtained in the software visualization process, and obtaining the coordinate of the left upper coroner of each node frame according to the search result; secondly, acquiring the frame length and width information of each node according to the set text content and type of each node; and finally, obtaining the coordinate of the central point of a frame rectangle according to the coordinate of the left upper corner of each node frame and the frame length and width information of each node. In the invention, when the digraph has a large number of nodes, the intercrossed lines are reduced as much as possible; and the layout of other nodes connected with a node in a geometric space is taken into full consideration, the positions of the nodes in the digraph are concentrated relatively, and the readability of a hierarchic system structure chart is high.

Description

technical field [0001] The invention relates to a graphic layout method, in particular to a graphic layout method suitable for a software visualization process, and belongs to the technical field of software visualization. Background technique [0002] Software visualization usually uses software automation to summarize various attributes of the software system (including keywords, inter-class relationships, etc.) The internal structure of the system, the evolution information of the software, and the behavioral characteristics of the software realize the automatic analysis and abstraction of the source code, and generate a highly generalized graphical representation that can reflect the internal structure of the software or other measurement information. By visualizing the software system, the high-level abstraction of the software can be obtained, and it is convenient to quickly obtain the understanding of the software design level. [0003] The significance of software v...
