Vue使用Echarts的三种实现方式

npm install echarts --save

<template>
  <div :style="{width: '100%', height: '300px'}" ref="chart"></div>
</template>
<script>
import echarts from 'echarts'
export default {
  name: 'EChart',
  props: {
    option: {
      type: Object,
      required: true
    }
  },
  data() {
    return {
      chartInstance: null
    }
  },
  watch: {
    option: {
      handler(newOption) {
        if (this.chartInstance) {
          this.chartInstance.setOption(newOption);
        }
      },
      deep: true
    }
  },
  mounted() {
    this.chartInstance = echarts.init(this.$refs.chart);
    this.chartInstance.setOption(this.option);
  },
  beforeDestroy() {
    if (this.chartInstance) {
      this.chartInstance.dispose();
    }
  }
}
</script>

<template>
  <div>
    <e-chart :option="chartOption"></e-chart>
  </div>
</template>
 
<script>
import EChart from './EChart.vue'
 
export default {
  components: {
    EChart
  },
  data() {
    return {
      chartOption: {
        // ECharts 配置项
      }
    }
  }
}
</script>
