本文实例为大家分享了vue+echarts实现堆叠柱状图的具体代码，供大家参考，具体内容如下
echarts-子组件
<template>
<div class="chart" ref="chartEle"></div>
</template>
<script>
import echarts from "echarts";
import eventBus from '@/components/event/event-bus'

}
},
data() {
return {
echartsObj: null,
}
},
mounted() {
var that = this
eventBus.$on("window-resize", target => {
that.echartsObj && that.echartsObj.resize()
});
},
methods: {
initCharts() {
this.echartsObj = echarts.init(this.$refs.chartEle)
this.setOption()
// window.onresize = function() {
// this.echartsObj.resize()
// }
},
resizeChart() {
this.echartsObj.resize()
},
setOption() {
const that = this
var option = {
color: ['#2DC6C8', '#B6A2DD'],
// tooltip: { trigger: 'item', formatter: "{a} : {c}" },
tooltip: { },
//右侧数据视图、折线图、还原、保存显示标志
toolbox: {

}
}
