在vue中我使用echarts作图代码如下 let dataMap = {}; //返回数据根据name分组 this.responseData.forEach(item => { if (!dataMap[item.nameWithIp]) { dataMap[item.nameWithIp] = { name: item.nameWithIp, type: 'line', data: [], }; } dataMap[item.nameWithIp].data.push({ value: [item.monitorDate, item[this.request.queueAttribute]], name: item.name, server:item.server, monitorDate: item.monitorDate, queueSize: item.queueSize, enqueueCount: item.enqueueCount, dequeueCount: item.dequeueCount, enqueueCountDiff: item.enqueueCountDiff, dequeueCountDiff: item.dequeueCountDiff, consumerCount: item.consumerCount, producerCount: item.producerCount, symbol: 'circle', // 配置标记样式 symbolSize: 4, // 配置标记大小 }); }); let seriesData = Object.values(dataMap); let myChartOptions = { tooltip: { trigger: 'item', axisPointer: { type: 'line', lineStyle: { color: '#999' } }, formatter: params => { let data = params.data; return 队列名称: ${data.name}<br/> 队列ip: ${data.server}<br/> 时间: ${data.monitorDate}<br/> 积压数: ${data.queueSize}<br/> 总生产数: ${data.enqueueCount}<br/> 生产数: ${data.enqueueCountDiff}<br/> 总消费数: ${data.dequeueCount}<br/> 消费数: ${data.dequeueCountDiff}<br/> 生产者数: ${data.consumerCount}<br/> 消费者数: ${data.producerCount} }, }, xAxis: { type: 'time', }, yAxis: { type: 'value', }, series: seriesData, }; let myChart = this.$echarts.init(document.getElementById("myChart")); myChart.clear(); myChart.setOption(myChartOptions) }, 代码中的this.request.queueAttribute是一个字符串，现在我将this.request.queueAttribute变为一个字符串数组，要求对其中的每个字符串实现原有的作图，即这个this.request.queueAttribute中有n个字符串，图中折线的数量就是原来的n倍，你告诉我作图部分代码应该怎么改

可以使用forEach遍历this.request.queueAttribute数组，将原有的作图代码放在forEach回调函数中执行，每次执行时将当前遍历到的字符串赋值给this.request.queueAttribute即可，代码如下：

let queueAttributes = this.request.queueAttribute;
queueAttributes.forEach(attribute => {
  let dataMap = {};
  this.responseData.forEach(item => {
    if (!dataMap[item.nameWithIp]) {
      dataMap[item.nameWithIp] = {
        name: item.nameWithIp,
        type: 'line',
        data: [],
      };
    }
    dataMap[item.nameWithIp].data.push({
      value: [item.monitorDate, item[attribute]],
      name: item.name,
      server: item.server,
      monitorDate: item.monitorDate,
      queueSize: item.queueSize,
      enqueueCount: item.enqueueCount,
      dequeueCount: item.dequeueCount,
      enqueueCountDiff: item.enqueueCountDiff,
      dequeueCountDiff: item.dequeueCountDiff,
      consumerCount: item.consumerCount,
      producerCount: item.producerCount,
      symbol: 'circle',
      symbolSize: 4,
    });
  });
  let seriesData = Object.values(dataMap);
  let myChartOptions = {
    tooltip: {
      trigger: 'item',
      axisPointer: {
        type: 'line',
        lineStyle: {
          color: '#999'
        }
      },
      formatter: params => {
        let data = params.data;
        return `队列名称: ${data.name}<br/>队列ip: ${data.server}<br/>时间: ${data.monitorDate}<br/>积压数: ${data.queueSize}<br/>总生产数: ${data.enqueueCount}<br/>生产数: ${data.enqueueCountDiff}<br/>总消费数: ${data.dequeueCount}<br/>消费数: ${data.dequeueCountDiff}<br/>生产者数: ${data.consumerCount}<br/>消费者数: ${data.producerCount}`;
      },
    },
    xAxis: {
      type: 'time',
    },
    yAxis: {
      type: 'value',
    },
    series: seriesData,
  };
  let myChart = this.$echarts.init(document.getElementById("myChart"));
  myChart.clear();
  myChart.setOption(myChartOptions)
});

这样修改后，作图部分的代码会根据this.request.queueAttribute数组中的每个字符串分别执行一次，生成对应的折线图。
