In the era of big data, the phrase we hear most often is “Speak with data”.

Data big screen is a very popular data visualization tool, which can visually display the key indicators of business on one or more LED large screens. It not only enables business personnel to quickly find important data from the complex business data, but also plays an auxiliary role for decision makers.

In the just-concluded PROMOTION of JINGdong 618, if you have the opportunity to walk into the JINGdong 618 combat command center, you will see the digital constantly changing monitoring screen and the technical staff of jingdong in each section of the battle, you will be surprised to find that using the data screen, we can spend a nearly perfect 618 everything under control.

In addition to the electric field, as a kind of effective means of passing information data screen, is the city intelligent operations center, emergency command center, the public security monitoring, electric power dispatching center, financial trading floors, and other departments and agencies play an important role, with daily monitoring, and to analysis report, emergency command, display and other functions, It plays an important role in improving scientific management.

The figure below shows a typical large-screen data case in a data center. The structure of the data center emerges in the dark background. The space utilization, power utilization, real-time PUE, and historical PUE are vividly and flexibly displayed by graphs and charts. In addition to bringing visual shock, data center operation and maintenance personnel can use data visualization to discover problems in a timely manner and solve faults based on alarm information to ensure smooth operation of the data center.

Many people’s first impression of big data screen is cool, but in fact, a qualified big data screen is not only cool effect, full of special effects. The main purpose of data large screen is to convey and communicate information clearly and effectively by means of graphics. Therefore, “clear and effective” is the key point of data big screen. There are so many visualization tools on the market today, some boring for the sake of functional effect, some extremely complex for the sake of color, that it is difficult for business decision makers to understand the true value of data.

Jd Zhaopin cloud data big screen can perfectly solve these two problems. It is a data visualization tool based on real-time multi-layer rendering technology, which can display massive data in real-time scenes and provide hierarchical data display functions. Users can fully master data through drilling, zooming and other interactive ways. At the same time, for users, JD Zhaopin cloud data large screen is also a graphical large screen development tool. Non-professional data engineers can also carry out wySIWYG visual processing of data by dragging and dropping, and quickly build their own cool large screen.

In order to achieve “clear and effective transmission and communication of information”, JD Zhaopin cloud data screen provides a rich tool library from data source, template to rich visual effect design, which can meet the various needs of users when building data screen.

As can be seen from the name of the big data screen, the core is “data”. No matter how beautiful the statistical graph or dynamic effect is, there will be no soul without data support. The key work is how to use good data, analyze good data, coupled with good data display, to build a large data screen naturally.

Jingdong Zhaopin cloud data screen supports multiple data source links, including Static data in Jason format, RDS cloud database, jingdong Zhaopin cloud data computing service and online API, etc., to meet users’ needs for real-time computing and monitoring of all kinds of big data and give full play to big data computing capabilities.

▲ Data source configuration

Jingdong at cloud data screen screen integrated use of the template color collocation, components, data level correlation design layout, and integrates a variety of industries and the scene of the implementation of the specific industry specific scene in case for the user to provide professional general solution, provide covers electricity sales, agriculture, health, logistics, government and other industry application more than professional templates, To a great extent, it can meet the display requirements of conference and exhibition, business monitoring, risk warning, geographic information analysis and other businesses.

In many large data screens, GIS has become a standard configuration. It is like a “digital sandbox”, which can intuitively and comprehensively understand the overall situation of a certain area on a map or a screen. Jd Zhaopin cloud data screen supports six types of maps, including 3D border map (China/world), 2D border map (China/world) and 2D/3D GIS map.

Each map component supports multi-layer data overlay, allowing users to overlay flying lines, 3D histogram, bubbles, tracks, and thermal effects on the same map. Each data display mode supports multiple series of service data. For example, you can use the color and shape of a scatter plot to represent different types of crops.

All maps support drilling. Boundary maps can drill down to districts and counties, and GIS maps can drill down to street boundaries. Users can also customize the center point and zoom level of the map after drilling. In the following example: The data screen before drill-down is shown on the left, and the data screen after clicking a certain area is shown on the right. In the 2D/3D boundary map drill-down event, you can drill-down the map step by step by clicking the mouse (the minimum drill-down granularity is district and county); If you need to go back to the next level, click on the blank area of the map area to go back.

In order to provide rich page display capabilities, data big screen is also connected to ECharts and other third-party libraries, which can provide rich visual charts. Such as conventional broken line chart, bar chart, scatter chart, pie chart, water level chart, radar chart, K chart, box chart, calendar thermal map, relationship chart, funnel chart, Mulberry chart, instrument panel and other charts, to meet the user’s multidimensional data analysis and display.

At the same time, through the open chart style editing function, you can achieve a variety of personalized effects of a component, such as providing flop, word cloud and other text components as well as GIF decorative components such as background frame. Also supports TAB TAB, map drill down, time picker and other interactive components, support multi-chart, component linkage and mixed display.

Now, a lot of data large screen is through multi-screen splicing to achieve the display effect of large screen. For the display of the splicing large screen, JD Zhilian cloud has made resolution optimization, which can adapt to various unconventional splicing resolution. At the same time, JD Zhaopin cloud data big screen adopts the data rendering capability of SVG + Canvas dual engine, and adopts CDN and object storage technology to optimize the loading and access speed of the big screen, so that the data big screen can run smoothly on PC and mobile devices.

After reading the above, you may be worried about the complexity of implementing so many features. In fact, do not worry at all, JINGdong Zhilian cloud data screen is completely suitable for ordinary business personnel, do not need to master database knowledge and front-end development ability, also do not need programming ability, you just need to drag and drop on jingdong Zhilian cloud, you can create a professional visual application.
