uniapp 多轴图，双轴图，指定哪几个数据在哪个轴上显示

这里使用的在这里导入，

秋云 ucharts echarts 高性能跨全端图表组件 - DCloud 插件市场

这里我封装成一个组件，自适应的，可以直接复制到自己的项目中

<template>
    <qiun-data-charts 
      type="mix"
      :opts="opts"
      :chartData="chartData"
    />
</template>

<script>
export default {
  data() {
    return {
      chartData: {},
      //您可以通过修改 config-ucharts.js 文件中下标为 ['mix'] 的节点来配置全局默认参数，如都是默认参数，此处可以不传 opts 。实际应用过程中 opts 只需传入与全局默认参数中不一致的【某一个属性】即可实现同类型的图表显示不同的样式，达到页面简洁的需求。
      opts: {
        color: ["#1890FF","#91CB74","#FAC858","#EE6666","#73C0DE","#3CA272","#FC8452","#9A60B4","#ea7ccc"],
        // padding: [15,15,15,15],
        enableScroll: false,
        legend: {},
        xAxis: {
          disableGrid: true,
          // title: "单位：年"
        },
        yAxis: {
          disabled: false,
          disableGrid: false,
          splitNumber: 5,
          gridType: "dash",
          dashLength: 4,
          gridColor: "#CCCCCC",
          padding: 10,
          showTitle: true,
          data: [
            {
              position: "left",
              title: "折线1"
            },
           {
             position: "right",
             title: "折线2",
			 // min: 0,
			 // max: 200,
           },
          ]
        },
        extra: {
          mix: {
            column: {
              width: 20
            }
          }
        }
      }
    };
  },

  methods: {
    getServerData() {
      //模拟从服务器获取数据时的延时
      setTimeout(() => {
        //模拟服务器返回数据，如果数据格式和标准格式不同，需自行按下面的格式拼接
        let res = {
            categories: ["2018","2019","2020","2021","2022","2023"],
            series: [
              {
				index: 0,
                name: "折线1",
                type: "line",
                style: "curve",
                color: "#1890ff",
                disableLegend: true,
                data: [70,50,85,130,64,88]
              },
              {
				  index: 1,
                name: "折线2",
                type: "line",
				style: "curve",
                color: "#2fc25b",
				disableLegend: true,
                data: [120,140,105,170,95,160]
              },
            ]
          };
        this.chartData = JSON.parse(JSON.stringify(res));
      }, 500);
    },
  },
  mounted(){
	   this.getServerData();
  }
};
</script>

<style scoped>
  /* 请根据实际需求修改父元素尺寸，组件自动识别宽高 */
  .charts-box {
    width: 100%;
    height: 100%;
  }
</style>

这里是配置有几个轴

yAxis: {
          disabled: false,
          disableGrid: false,
          splitNumber: 5,
          gridType: "dash",
          dashLength: 4,
          gridColor: "#CCCCCC",
          padding: 10,
          showTitle: true,
          data: [
//配置有几个轴
            {
              position: "left",
              title: "折线1"
            },
           {
             position: "right",
             title: "折线2",
			 // min: 0,
			 // max: 200,
           },
          ]
        },

?配置在哪个轴上面，index? 0是第一个? index:1 指的是第二个，依次类推

series: [
              {
				index: 0, // 配置第几个轴
                name: "折线1",
                type: "line",
                style: "curve",
                color: "#1890ff",
                disableLegend: true,//是否在legend中显示，默认不显示
                data: [70,50,85,130,64,88]
              },
              {
				  index: 1,
                name: "折线2",
                type: "line",
				style: "curve",
                color: "#2fc25b",
				disableLegend: true,
                data: [120,140,105,170,95,160]
              },
            ]
