Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of data visualization, in particular to a data visualization method and system. BACKGROUND

[0002] With the continuous development of enterprise business, a large amount of business data has been accumulated, which contains rich information and potential value. However, simple data storage and management cannot directly translate into decision support for enterprises. Enterprises need to use effective data analysis methods to mine the value behind the data. Data visualization, as an intuitive and efficient data analysis method, can display complex data in the form of graphs, charts, etc., helping users quickly understand the distribution, trend and correlation of data, thereby providing strong support for enterprise decision-making. Therefore, data visualization systems have emerged as the best solution to the needs of enterprise mass data management and analysis, which not only helps enterprises better utilize data resources, but also improves the operational efficiency and competitiveness of enterprises.

[0003] The current data visualization system uses fixed dimension and index concept to associate data sets when making visualization components, so it can only process data sets with dimension and index structure, such as line charts and column charts, but cannot make charts with complex data structures that cannot be described by dimensions or indexes (such as relationship charts, box charts, geographic coordinates and line combination charts), limiting the types of charts that the system can support and expand.

[0004] Chinese patent CN113886664A "Data visualization method and system based on data label type chart plug-in" sets a visualization plug-in containing data labels and drawing functions, and the data label binding information in the chart information is used to extract chart data from the data set and execute chart drawing, so as to realize the drawing of charts with complex data structures. However, in some cases, users need to draw and display multiple data sets with different structures in one visualization component, such as data set 1 containing fields: region name, sales, and data set 2 containing fields: longitude, latitude, region name, sales, which requires them to be drawn in one chart, with data set 1 drawn as a column chart and data set 2 drawn as a map. However, in the prior art, one visualization plug-in can only associate one data set scenario, and multiple different visualization types of data set chart drawing need to be drawn multiple times and using different visualization plug-ins, which makes the operation complex.

[0031] Step S1: in response to the selected pre-defined visualization plug-in command input by the user, adding the selected pre-defined visualization plug-in to the chart to be generated; the visualization plug-in includes basic description information, a renderer, and a data name card; the data name card includes: a plurality of data set name cards and field name cards; the data set name card is used to describe the generation chart demand of the data set; the field name card is used to describe the field attribute in the data set; and the generation chart demand includes the generation chart type.

[0032] In step S1, the visualization plug-in is independent of the visualization system, is implemented by the plug-in developer, can be installed into the visualization system, and draws the visualization component. In addition to defining the basic identification and description information and the renderer containing executable code for drawing the visualization component, the visualization plug-in also defines the data name card information.

[0033] The data name card has two types: data set name card and field name card. The data set name card is composed of name, description and other information, and is used to mark the data set. One visualization plug-in can contain multiple data set name cards. The field name card is composed of name, description, and the data set name card to which it belongs, and is used to mark the field in the data set. One visualization plug-in can contain multiple field name cards. The data set name card to which the field name card belongs is optional information. If it is set, it can only mark the data set field marked with the data set name card. If it is not set, it can mark any data set field.

[0034] The user opens the visualization component definition operation interface of the visualization system, and selects a plug-in to be used from the visualization plug-ins installed in the system.

[0035] The generation chart requirement includes a chart type to be generated, i.e. a column chart, a sector, a map, etc. Field attributes such as month, sales, etc.

[0041] In step S4, the visualization system loads the renderer of the selected plug-in of the visualization component, reads the data of the selected data set of the visualization component, and passes the data card marking information to the plug-in renderer together. The plug-in renderer reads the data set information marked by the specified data set card according to the data card marking information, reads the field information of the data set marked by the specified field card, then reads the corresponding data set data according to the data set field information, constructs drawing data, and draws the visualization component in the interface.
