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]},]
