已经解决

代码如下

<template>
  <div :class="className" :style="{height:height,width:width}" />
</template>

<script>
import echarts from 'echarts'
require('echarts/theme/macarons') // echarts theme
import resize from './mixins/resize'
import {loadHistogram} from '@/api/loadInfo'

const animationDuration = 6000

export default {
  mixins: [resize],
  props: {
    className: {
      type: String,
      default: 'chart'
    },
    width: {
      type: String,
      default: '100%'
    },
    height: {
      type: String,
      default: '300px'
    }
  },
  data() {
    return {
      chart: null,
      dataInfo:[],
    }
  },
  mounted() {
    this.$nextTick(() => {
      this.DoloadHistogram();
      this.initChart()
    })
  },
  beforeDestroy() {
    if (!this.chart) {
      return
    }
    this.chart.dispose()
    this.chart = null
  },
  methods: {
    DoloadHistogram(){
      loadHistogram().then(
        responese =>{
          this.dataInfo = responese.data;
          this.initChart(this.dataInfo);
        }
      );

    initChart(dataInfo) {
      this.chart = echarts.init(this.$el, 'macarons')

        }],
        yAxis: [{
          type: 'value',
          axisTick: {
            show: false
          }
        }],
        series: [{
