vue中使用Echars

1.安装依赖

• vue2.0框架

npm install echarts

• vue3.0框架

npm add echarts

2.引入相关文件

· 全局引入

在 min.js 中引入 import echarts from 'echarts Vue.prototype.$echarts = echarts

· 按需引入

在单个组件中引用

// echarts 按需引入
let echarts2 = require('echarts/lib/echarts')
 
// 引入折线图等组件
require('echarts/lib/chart/line')
require('echarts/lib/chart/bar')
require('echarts/lib/chart/radar')
 
// 引入提示框和title组件，图例
require('echarts/lib/component/tooltip')
require('echarts/lib/component/title')
require('echarts/lib/component/legend')
 
Vue.prototype.$echarts2 = echarts2

3.代码示例

<template>
  <div class="app">
    <div id="box" class="bos"></div>
  </div>
</template>
<script>
export default {
  name: "app",
  components: {},
  mounted() {
    this.initChart();
  },
  data() {
    return {};
  },
  methods: {
    initChart() {
      let bos = this.$echarts.init(document.getElementById("box"));

      // 绘制图表
      bos.setOption(this.setOption1("我是柱状图"));
    },
    setOption1(title) {
      let option = {
        title: { text: title },
        tooltip: {},
        xAxis: {
          data: ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"]
        },
        yAxis: {},
        series: [
          {
            name: "销量",
            type: "bar",
            data: [5, 20, 36, 10, 10, 20]
          }
        ]
      };
      return option;
    }
  }
};
</script>
<style scoped>
  .bos {
    width: 500px;
    height: 300px;
    margin: 0 auto;
  }
</style>
