封装一个echarts的组件

父组件页面

<yyjlchartv-if="showyyjl"chartId="yyjllLine":sourceData="sourceDatayyjl":options="optionsyyjl"></yyjlchart>

components: {LineEcharts,yyjlchart: () => import("../yyjlchart"),},data() {return {showyyjl: false,optionsyyjl: {grid: {left: "3%",right: "3%",bottom: "10%",top: "1%",},},
},methods: {async yyjlmap() {this.showyyjl = false;xxx调接口
数据返回后this.sourceDatayyjl.xdata = res.data.xData;this.sourceDatayyjl.ydata = res.data.medicateNames.reverse();this.sourceDatayyjl.result[0].data = res.data.yData.reverse();this.showyyjl = true;}
