vuejs中使用echart圖表

首先安裝echart
npm i echarts -S
加下來以使用這個圖表爲例
在vue組件中像這樣使用：

<template>
  <div :class="className" :id="id" :style="{height:height,width:width}" ref="myEchart">
  </div>
</template>
<script>
import echarts from 'echarts'
export default {
  props: {
    className: {
      type: String,
      default: 'yourClassName'
    },
    id: {
      type: String,
      default: 'yourID'
    },
    width: {
      type: String,
      default: '500px'
    },
    height: {
      type: String,
      default: '500px'
    }
  },
  data() {
    return {
      chart: null
    }
  },
  mounted() {
    this.initChart();
  },
  beforeDestroy() {
    if (!this.chart) {
      return
    }
    this.chart.dispose();
    this.chart = null;
  },
  methods: {
    initChart() {
      this.chart = echarts.init(this.$refs.myEchart);
      // 把配置和數據放這裏
      this.chart.setOption({
        color: ['#3398DB'],
        tooltip: {
          trigger: 'axis',
          axisPointer: { // 座標軸指示器，座標軸觸發有效
            type: 'shadow' // 默認爲直線，可選爲：'line' | 'shadow'
          }
        },
        grid: {
          left: '3%',
          right: '4%',
          bottom: '3%',
          containLabel: true
        },
        xAxis: [{
          type: 'category',
          data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'],
          axisTick: {
            alignWithLabel: true
          }
        }],
        yAxis: [{
          type: 'value'
        }],
        series: [{
          name: '直接訪問',
          type: 'bar',
          barWidth: '60%',
          data: [10, 52, 200, 334, 390, 330, 220]
        }]
      })
    }
  }
}
</script>

若是是異步獲取的數據，好比用axios,那隻須要把配置項放到then方法後面：

initChart() {
      this.chart = echarts.init(this.$refs.myEchart);
      // 把配置和數據放這裏
      this.axios.get('/url').then((data) => {
        this.chart.setOption({

        })
      })
    }
