vue使用echarts

 

npm install echarts -S

main.js
import echarts from 'echarts'
Vue.prototype.$echarts = echarts


echart.vue
<template>
    <div>
      <div id="myChart" :style="{width: '300px', height: '300px'}"></div>
    </div>
</template>

<script>
export default {
  name: 'myChart',
  data () {
    return {
      msg: 'Welcome to Your Vue.js App'
    }
  },
  mounted(){
    this.drawLine();
  },
  methods: {
    drawLine(){
        // 基於準備好的dom，初始化echarts實例
        let myChart = this.$echarts.init(document.getElementById('myChart'))
        // 繪製圖表
        myChart.setOption({
            title: { text: '在Vue中使用echarts' },
            tooltip: {},
            xAxis: {
                data: ["襯衫","羊毛衫","雪紡衫","褲子","高跟鞋","襪子"]
            },
            yAxis: {},
            series: [{
                name: '銷量',
                type: 'bar',
                data: [5, 20, 36, 10, 10, 20]
            }]
        });
    }
  }
}
</script>

<style lang="">
    
</style>

注意：我們要在mounted生命週期函數中實例化echarts對象。因爲我們要確保dom元素已經掛載到頁面中
