Abstract:Large-screen data visualization is an expression of data analysis results and an important part of data-enabled decision making. Given the long development cycle and high cost of large-screen data visualization software, an easy-to-use large-screen data visualization tool C317DataUI is developed on the basis of the Vue front-end framework and the Echarts visual components. The interface layout of the visual components is conducted by drag-and-drop operation, and data configuration management is carried out via the data connection panel of the components. The tool also provides some scene templates that can quickly deliver the expression of large-screen data visualization and thereby meet the needs of industrial users for data visualization with a low cost and a high efficiency.
