Data visualization method and device and computer readable medium

Abstract

The invention provides a data visualization method and device and a computer readable medium. The method comprises the following steps: when an editing instruction input by a user through the front-end page is received, executing the following operations: creating an entity canvas in the front-end page, creating at least one visualization module in the entity canvas, calculating a first minimum cardinal number when each visualization module moves along a first direction of the entity canvas and a second minimum cardinal number when each visualization module moves along a second direction of the entity canvas; and for each visualization module, creating a chart in the visualization module, and when an adjustment instruction sent by a user is received, adjusting a target visualization modulecorresponding to the adjustment instruction according to the adjustment instruction, the first minimum cardinal number and the second minimum cardinal number. According to the visualization module created by the scheme, the chart is obtained through rendering on the visualization module, and the visualization module is adjusted according to user requirements, so that the problems of long development period, high maintenance cost and complex and difficult modification of data visualization can be solved.

Description

technical field [0001] The present invention relates to the technical field of big data visualization, in particular to a data visualization method, device and computer readable medium. Background technique [0002] At present, big data visualization is one of the most effective and intuitive means of displaying data, but conventional data visualization construction methods often require cumbersome design and development processes. [0003] The current construction of data visualization generally includes the following methods: [0004] The process of data acquisition and visualization is usually developed into a unified style of display by means of code customization. The disadvantage of this approach is that each change requires immersion modification of the system code to complete, and the change involves many people and is complicated. It is equivalent to redeveloping a set of different statistical dimensions and presentation methods. [0005] Therefore, to address the...
