在src目录下建立utils文件建立tooltip-auto-show-vue.js

export function autoHover(myChart, option, num, time) {var defaultData = {// 设置默认值time: 2000,num: 100}if (!time) {time = defaultData.time}if (!num) {num = defaultData.num}var count = 0var timeTicket = nulltimeTicket && clearInterval(timeTicket)timeTicket = setInterval(function () {myChart.dispatchAction({type: 'downplay',seriesIndex: 0 // serieIndex的索引值   可以触发多个})myChart.dispatchAction({type: 'highlight',seriesIndex: 0,dataIndex: count})myChart.dispatchAction({type: 'showTip',seriesIndex: 0,dataIndex: count})count++if (count >= num) {count = 0}}, time)myChart.on('mouseover', function (params) {clearInterval(timeTicket)myChart.dispatchAction({type: 'downplay',seriesIndex: 0})myChart.dispatchAction({type: 'highlight',seriesIndex: 0,dataIndex: params.dataIndex})myChart.dispatchAction({type: 'showTip',seriesIndex: 0,dataIndex: params.dataIndex})})myChart.on('mouseout', function () {timeTicket && clearInterval(timeTicket)timeTicket = setInterval(function () {myChart.dispatchAction({type: 'downplay',seriesIndex: 0 // serieIndex的索引值   可以触发多个})myChart.dispatchAction({type: 'highlight',seriesIndex: 0,dataIndex: count})myChart.dispatchAction({type: 'showTip',seriesIndex: 0,dataIndex: count})count++if (count >= 17) {count = 0}}, 3000)})
}
export default {autoHover
}

在需要的文件中引入

import { autoHover  } from "../utils/tooltip-auto-show-vue"; // 文件位置参考自己的位置

//tooltip 轮播
autoHover(myChart, option, 4, 3000); // 参数分别为：容器，配置，轮播数量，轮播间隔时间window.addEventListener('resize', myChart.resize);})
