Problems solved by technology
However, the semantic tree obtained based on ANTLR analysis contains multiple abstract concepts such as grammar, lexical, logical operators, and conditional operators defined by the grammar file. It is difficult for users to understand and understand the interface display, especially when the custom grammar structure is more When it is complex, such as when multiple logical operators exist and are nested with each other, there are unnecessary multiple layers of nesting based on the semantics parsed by ANTLR, and the final tree structure will be very large and difficult to understand and display. It can be seen , the existing ANTLR-based visual display methods for logical expressions have shortcomings such as complex structure, poor visualization effect, and unclear expression

The invention discloses a data visualization method. The method comprises the steps: converting a to-be-processed logic expression into an ANTLR syntax tree by utilizing an ANTLR tool; converting theANTLR syntax tree by adopting a visitor mode to obtain an initial visualization model; optimizing the priority information in the initial visualization model to obtain an optimized visualization model; merging similar item information in the optimized visual model to obtain a tree model; and outputting the tree-shaped model to visual equipment to be displayed. According to the data visualization method, the visualization structure of the logic expression can be more effectively simplified, and the visualization effect is improved. The invention furthermore discloses a data visualization apparatus and device, and a computer readable storage medium, which all have the above beneficial effects.
Description
technical field [0001] The present application relates to the field of information technology, in particular to a data visualization method, and also to a data visualization device, device, and computer-readable storage medium. Background technique [0002] In the process of visual display of logical expressions, the most important point is to correctly analyze the logical expressions, that is, the final visual display can correctly and intuitively express the logical expressions input by the user. [0003] At present, some specific parsing tools are usually used for semantic parsing, such as ANTLR (ANother Toolfor Language Recognition), ANTLR is a powerful parser generator, which is widely used to build languages, tools and frameworks, which can realize reading , process, execute or translate structured text or binary files. However, the semantic tree obtained based on ANTLR analysis contains multiple abstract concepts such as grammar, lexical, logical operators, and condi...
