vue使用echarts图表自适应的几种解决方案

let myChart = echarts.init(document.getElementById(dom))
window.onresize = function () {
 	myChat.resize()
}

let myChart1 = echarts.init(document.getElementById(dom1))
let myChart2 = echarts.init(document.getElementById(dom2))
window.onresize = function () {
 	myChat1.resize()
 	myChat2.resize()
}

let myChart = echarts.init(document.getElementById(dom))
let sizeFun = function () {
 	myChat.resize()
}
window.addEventListener('resize', sizeFun )
