From entry to mastery: Use ECharts and golang to create practical statistical charts
Introduction:
In the modern data-driven era, statistical charts are the key to our understanding and One of the important tools for displaying data. With statistical charts, we can more intuitively observe the trends, distributions and relationships of data. This article will introduce how to use ECharts and golang, two powerful tools, to create practical statistical charts, and will provide specific code examples.
1. Introduction to ECharts
- Overview of ECharts
ECharts is an excellent data visualization tool open sourced by Baidu. It supports a variety of chart types, including line charts and bar charts. , pie chart, etc. ECharts provides powerful functions, such as dynamic updating of data, linkage of data, and switching between multiple charts. - Features of ECharts
- Easy to use: ECharts provides detailed documentation and rich examples, making it easy for beginners to get started.
- Highly customizable: ECharts provides a wealth of configuration items and styles to customize the appearance and behavior of charts according to your needs.
- Supports multiple platforms: ECharts can be displayed in the browser and can also be used in platforms such as Node.js and React Native.
2. Use of golang
- golang overview
golang is a programming language for developing efficient and reliable back-end applications. It has easy-to-learn syntax and powerful concurrency performance, making it an ideal choice for writing high-performance web applications and server-side tools. - The combination of golang and ECharts
The combination of golang and ECharts can effectively realize data processing and chart display. Through golang, you can read data in the database, perform data processing, and pass the processed data to ECharts for chart generation.
3. Sample code
The following is a simple example showing how to use golang and ECharts to make a line chart:
package main import ( "net/http" "log" "github.com/gin-gonic/gin" ) func main() { router := gin.Default() router.LoadHTMLGlob("templates/*") router.GET("/", func(c *gin.Context) { c.HTML(http.StatusOK, "index.tmpl", gin.H{ "title": "折线图示例", "data": []int{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, }) }) if err := router.Run(":8080"); err != nil { log.Fatal("服务器启动失败") } }
In the above code, we use gin framework to create a web server. When the user accesses the root path, the data we pass to the template engine (index.tmpl) contains the title and data. In the template engine, we can use the ECharts JavaScript library to generate a line chart.
4. Summary and Outlook
This article introduces how to use ECharts and golang to create practical statistical charts. By combining these two tools, we can efficiently process and visualize data. In the future, we can further explore the functions of ECharts and golang, implement more types of charts, and use them in a wider range of fields.
Conclusion:
Statistical charts are an indispensable part of data analysis. Using ECharts and golang to create practical statistical charts will bring us more convincing visual results. I hope the content of this article will be helpful to readers and inspire more creativity and ideas. Let’s continue to explore the infinite possibilities of data visualization together!

How to configure connection pooling for Go database connections? Use the DB type in the database/sql package to create a database connection; set MaxOpenConns to control the maximum number of concurrent connections; set MaxIdleConns to set the maximum number of idle connections; set ConnMaxLifetime to control the maximum life cycle of the connection.

JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.

The difference between the GoLang framework and the Go framework is reflected in the internal architecture and external features. The GoLang framework is based on the Go standard library and extends its functionality, while the Go framework consists of independent libraries to achieve specific purposes. The GoLang framework is more flexible and the Go framework is easier to use. The GoLang framework has a slight advantage in performance, and the Go framework is more scalable. Case: gin-gonic (Go framework) is used to build REST API, while Echo (GoLang framework) is used to build web applications.

Go framework development FAQ: Framework selection: Depends on application requirements and developer preferences, such as Gin (API), Echo (extensible), Beego (ORM), Iris (performance). Installation and use: Use the gomod command to install, import the framework and use it. Database interaction: Use ORM libraries, such as gorm, to establish database connections and operations. Authentication and authorization: Use session management and authentication middleware such as gin-contrib/sessions. Practical case: Use the Gin framework to build a simple blog API that provides POST, GET and other functions.

Go language performs well in building efficient and scalable systems. Its advantages include: 1. High performance: compiled into machine code, fast running speed; 2. Concurrent programming: simplify multitasking through goroutines and channels; 3. Simplicity: concise syntax, reducing learning and maintenance costs; 4. Cross-platform: supports cross-platform compilation, easy deployment.
