Embodiment 1

[0027] figure 1 This is a flowchart of the chart visualization method provided in the first embodiment of the present invention. This embodiment is applicable to the case of data statistical analysis. The method may be executed by a chart visualization device, which may be configured in a user terminal, for example. Such as figure 1 As shown, the method specifically includes:

[0028] S110. In response to a fetch instruction, connect to a data source and obtain metadata, where the metadata is field data of data to be processed in the data source.

[0029] Among them, the data source is the database. In the embodiment of the present invention, multiple types of databases, such as MySQL, ES, Kylin, Hbase, etc., can be supported. Specifically, MySQL is a relational database, and ES (ElasticSearch) is a distributed Full-text retrieval framework, Kylin is an open source distributed analysis engine that provides SQL query interface and multidimensional analysis (OLAP) on Hadoop / Spark to ...

Embodiment 2

[0043] figure 2 It is a schematic structural diagram of a chart visualization device provided in the second embodiment of the present invention. This embodiment can be applied to the situation of data statistical analysis. Such as figure 2 As shown, the device includes: a metadata acquisition module 210, a template display module 220, a program sending module 230, and a chart rendering module 240.

[0044] Among them, the metadata acquisition module 210 is used to respond to the fetch instruction, connect to the data source and obtain metadata, the metadata is the field data of the data to be processed; the template display module 220 is used to select the chart type according to the user Provide a corresponding chart field template for the user to configure chart field attributes in the chart field template according to the metadata; the program sending module 230 is used to send the chart type selected by the user in response to the chart generation instruction The data proce...

Embodiment 3

[0053] image 3 It is a schematic structural diagram of a terminal in Embodiment 3 of the present invention. image 3 A block diagram of an exemplary terminal 312 suitable for implementing embodiments of the present invention is shown. image 3 The displayed terminal 312 is only an example, and should not bring any limitation to the function and application scope of the embodiment of the present invention.

[0054] Such as image 3 As shown, the terminal 312 is in the form of a general-purpose computing device. The components of the terminal 312 may include, but are not limited to: one or more processors or processing units 316, a system memory 328, and a bus 318 connecting different system components (including the system memory 328 and the processing unit 316).

[0055] The bus 318 represents one or more of several types of bus structures, including a memory bus or a memory controller, a peripheral bus, a graphics acceleration port, a processor, or a local bus using any bus st...

Abstract

The embodiment of the invention discloses a chart visualization method and device, a terminal and a storage medium. The method comprises the steps of connecting a data source to obtain metadata in response to a data fetching instruction; according to the type of a chart selected by a user, providing a corresponding chart field template to help the user to configure chart field attributes in the chart field template according to the metadata; sending a data processing program matched with the type of the chart selected by the user to the connected data source in response to a chart generating instruction, wherein the data processing program is used for operating to-be-processed data in the data source according to the field attributes configured by the user; receiving an operation result ofthe data processing program, and rendering the operation result to obtain the chart. According to the embodiment, the problem is solved that the visualized development efficiency is low when the datasource is connected and data is loaded, it is achieved that the data can be not loaded to the local in the chart visualization process, the operation is completed in the data source, the chart visualization efficiency is improved, and the user experience is improved.

Description

Technical field [0001] The embodiments of the present invention relate to big data processing, and in particular to a chart visualization method, device, terminal and storage medium. Background technique [0002] Data chart visualization refers to the process of representing the data in a large data set in the form of graphics and images, and using data analysis and development tools to discover unknown information. [0003] At present, chart visualization tools include: Excel, tableau, Infogram, pictochart, Baidu Tushuo, NetEase Youshu, echart, etc., according to whether the database can be connected to two categories: one is based on open source or online editing, not connected to the database, import Or paste the summary data in excel format for visual display, which is simple and easy to operate; the other is mainly business chart visualization software, connects to the database, loads the data to the memory or local, supports simple summary, and performs visual display, which ...
