npm install -g @vue/cli
npm install echarts echarts-for-taro3

vue create my-project
cd my-project
npm install echarts-for-taro3

<template>
  <div ref="chart" class="echarts-container"></div>
</template>

<script>
import { init } from 'echarts-for-taro3';

export default {
  name: 'ECharts',
  props: {
    option: {
      type: Object,
      required: true
    }
  },
  mounted() {
    this.chart = init(this.$refs.chart);
    this.setOption();
  },
  methods: {
    setOption() {
      this.chart.setOption(this.option);
    }
  }
};
</script>

<style scoped>
.echarts-container {
  width: 100%;
  height: 100%;
}
</style>

<template>
  <div>
    <h2>柱状图</h2>
    <ECharts :option="chartOption" :loading="loading" />
  </div>
</template>

import ECharts from './ECharts.vue';

export default {

            animationDelay: function (idx) {
              return idx * 50;
            }
