How to draw an annual chart showing daily values ​​with ECharts?

Use ECharts to visually display the annual trend of daily data changes

Many data analysis scenarios require the daily data to be presented in a clear and intuitive way. This article will guide you how to use ECharts to create an annual chart. This chart uses 0-30 as the vertical axis values ​​and uses January 1 to December 31 as the horizontal axis dates, perfectly showing the fluctuations of daily values ​​throughout the year.

ECharts' powerful calendar coordinate system (calendar) functionality is the ideal tool for solving such problems. It can map data to each date cell of the calendar, visually displaying data changes in the form of a calendar.

With ECharts' calendar coordinate system, you can easily create the charts you want. Just use the 0-30 value as the data value and the dates from January 1 to December 31 as the data dimensions. ECharts will automatically map the data to the calendar to generate a clear annual data visualization effect. You can customize the color, marking and other styles of the chart according to your needs. The official ECharts website provides rich documentation and code examples to help you get started quickly.

With ECharts' calendar coordinate system, you will efficiently and easily create charts that clearly show the annual trends of daily numerical values.

The above is the detailed content of How to draw an annual chart showing daily values ​​with ECharts?. For more information, please follow other related articles on the PHP Chinese website!

How to use the chrono library in C? How to use the chrono library in C? Apr 28, 2025 pm 10:18 PM

Using the chrono library in C can allow you to control time and time intervals more accurately. Let's explore the charm of this library. C's chrono library is part of the standard library, which provides a modern way to deal with time and time intervals. For programmers who have suffered from time.h and ctime, chrono is undoubtedly a boon. It not only improves the readability and maintainability of the code, but also provides higher accuracy and flexibility. Let's start with the basics. The chrono library mainly includes the following key components: std::chrono::system_clock: represents the system clock, used to obtain the current time. std::chron

How to optimize code How to optimize code Apr 28, 2025 pm 10:27 PM

C code optimization can be achieved through the following strategies: 1. Manually manage memory for optimization use; 2. Write code that complies with compiler optimization rules; 3. Select appropriate algorithms and data structures; 4. Use inline functions to reduce call overhead; 5. Apply template metaprogramming to optimize at compile time; 6. Avoid unnecessary copying, use moving semantics and reference parameters; 7. Use const correctly to help compiler optimization; 8. Select appropriate data structures, such as std::vector.

How to measure thread performance in C? How to measure thread performance in C? Apr 28, 2025 pm 10:21 PM

Measuring thread performance in C can use the timing tools, performance analysis tools, and custom timers in the standard library. 1. Use the library to measure execution time. 2. Use gprof for performance analysis. The steps include adding the -pg option during compilation, running the program to generate a gmon.out file, and generating a performance report. 3. Use Valgrind's Callgrind module to perform more detailed analysis. The steps include running the program to generate the callgrind.out file and viewing the results using kcachegrind. 4. Custom timers can flexibly measure the execution time of a specific code segment. These methods help to fully understand thread performance and optimize code.

What is real-time operating system programming in C? What is real-time operating system programming in C? Apr 28, 2025 pm 10:15 PM

C performs well in real-time operating system (RTOS) programming, providing efficient execution efficiency and precise time management. 1) C Meet the needs of RTOS through direct operation of hardware resources and efficient memory management. 2) Using object-oriented features, C can design a flexible task scheduling system. 3) C supports efficient interrupt processing, but dynamic memory allocation and exception processing must be avoided to ensure real-time. 4) Template programming and inline functions help in performance optimization. 5) In practical applications, C can be used to implement an efficient logging system.

How to use string streams in C? How to use string streams in C? Apr 28, 2025 pm 09:12 PM

The main steps and precautions for using string streams in C are as follows: 1. Create an output string stream and convert data, such as converting integers into strings. 2. Apply to serialization of complex data structures, such as converting vector into strings. 3. Pay attention to performance issues and avoid frequent use of string streams when processing large amounts of data. You can consider using the append method of std::string. 4. Pay attention to memory management and avoid frequent creation and destruction of string stream objects. You can reuse or use std::stringstream.

What is static analysis in C? What is static analysis in C? Apr 28, 2025 pm 09:09 PM

The application of static analysis in C mainly includes discovering memory management problems, checking code logic errors, and improving code security. 1) Static analysis can identify problems such as memory leaks, double releases, and uninitialized pointers. 2) It can detect unused variables, dead code and logical contradictions. 3) Static analysis tools such as Coverity can detect buffer overflow, integer overflow and unsafe API calls to improve code security.

How to understand DMA operations in C? How to understand DMA operations in C? Apr 28, 2025 pm 10:09 PM

DMA in C refers to DirectMemoryAccess, a direct memory access technology, allowing hardware devices to directly transmit data to memory without CPU intervention. 1) DMA operation is highly dependent on hardware devices and drivers, and the implementation method varies from system to system. 2) Direct access to memory may bring security risks, and the correctness and security of the code must be ensured. 3) DMA can improve performance, but improper use may lead to degradation of system performance. Through practice and learning, we can master the skills of using DMA and maximize its effectiveness in scenarios such as high-speed data transmission and real-time signal processing.

How to implement loosely coupled design in C? How to implement loosely coupled design in C? Apr 28, 2025 pm 09:42 PM

To implement loose coupling design in C, you can use the following methods: 1. Use interfaces, such as defining the Logger interface and implementing FileLogger and ConsoleLogger; 2. Dependency injection, such as the DataAccess class receives Database pointers through the constructor; 3. Observer mode, such as the Subject class notifies ConcreteObserver and AnotherObserver. Through these technologies, dependencies between modules can be reduced and code maintainability and flexibility can be improved.
