How to achieve the circular addition of data in echarts…

To achieve the looping addition of data to Echarts series, you can use the setOption method of Echarts to accomplish this. The specific steps are as follows:

1. Create an array variable to store the data to be added.
2. Use a for loop to iterate through the data to be added, and add the data to an array variable.
3. After the loop finishes, update the echarts configuration by using the setOption method to set the array variable as the data attribute value of the series.

Here is an example code:

// 定义一个空数组，用来存储要添加的数据
var dataToAdd = [];

// 使用for循环遍历要添加的数据，将数据添加到数组中
for (var i = 0; i < 10; i++) {
  dataToAdd.push(Math.random() * 100);
}

// 使用setOption方法将数组作为series的data属性值，更新echarts的配置
myChart.setOption({
  series: [
    {
      name: '系列名',
      type: 'line',
      data: dataToAdd
    }
  ]
});

In this example, we use a for loop to generate 10 random numbers, then add these numbers to the dataToAdd array. Finally, we use the setOption method to set the array as the data property value for the series, updating the configuration of Echarts and achieving the addition of data in a loop.
