Multi-chart linkage model construction method and linkage method in data visualization

Abstract

The invention discloses a multi-chart linkage model construction method and linkage method in data visualization, and the construction method comprises the steps: modeling a data visualization assembly, and extracting parameters and dimensions from the data rendered by the data visualization assembly; constructing a linkage relation table by using the parameters and dimensions of the data visualization component; and adjusting the linkage relation table by using a preset mechanism according to different scenes. According to the multi-chart linkage model construction method provided by the invention, complicated multi-chart linkage configuration is enabled to be code-free; and compared with a traditional automatic linkage BI tool, the data configuration flexibility is enriched, and compared with data visualization application of personalized development, the data development and maintenance cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of data visualization, and more specifically, to a method for building a multi-chart linkage model and a linkage method in data visualization. Background technique [0002] When doing data visualization, multiple different chart components are usually used to visualize data in multiple dimensions and perspectives. When multiple chart components jointly display high-dimensional information, the linkage operation between multiple charts initiated based on keyboard and mouse behavior events is a common way of human-computer interaction. At present, there are two types of linkage settings for chart linkage in common data visualization systems: "automatic" linkage and development. [0003] Microsoft has implemented a fully automatic linkage relationship in the perspective function of Excel, which is suitable for most simple scenarios. Its principle is to extract the same common filter conditions among m...

However, this fully personalized linkage configuration is expensive and not easy to maintain

[0005] In the prior art, the Chinese invention patent with the publication number CN104572096A disclosed a WEB-based multi-model data visualization development method and platform on April 29, 2015. The scheme abstracts rules for different types of data visualization models, Using a unified metadata schema to describe and develop different types of visual components is an effective way to reduce development and maintenance costs. However, this method pays more attention to the metadata itself and does not specifically propose multi-chart linkage. The solution does not solve the contradiction between "low code" and "high flexibility"
