我是靠谱客的博主大意皮带，最近开发中收集的这篇文章主要介绍vue+echarts实现堆叠柱状图，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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'

        default: []
      },
      xAxisData: {
        type: Array,
        default: []
      },
      seriesData: {
        type: Array,
        default: []
      }

    },

    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()
      },

        const that = this
        var option = {
