在Vue中使用antv的示例代码

一，在vue原型中使用

1.首先安装antv/g2

yarn add @antv/g2 --save

2.在main.js中挂在到vue原型实例中

const G2 = require('@antv/g2')
Vue.prototype.$G2 = G2

3.在vue文件中可以直接在mounted生命周期中直接使用

<template>
 <div>
  <div id="c1"></div>
 </div>
</template>

<script>
export default {
 mounted() {
  this.initComponent();
 },
 data() {
  return {
   msg: "",
   chart: null,
   data: [
    { genre: "Sports", sold: 275 },
    { genre: "Strategy", sold: 115 },
    { genre: "Action", sold: 120 },
    { genre: "Shooter", sold: 350 },
    { genre: "Other", sold: 150 }
   ]
  };
 },
 methods: {
  initComponent() {
   const chart = new this.$G2.Chart({
    container: "c1",
    width: 600,
    height: 300
   });
   chart.source(this.data);
   chart
    .interval()
    .position("genre*sold")
    .color("genre");
   this.chart = chart;
   this.chart.render();
  }
 }
};
</script>

二，按需引用

1.还是安装atv/g2

yarn add @antv/g2 --save

2.直接在组件中按需引入

<template>
 <div>
  <div id="l1"></div>
 </div>
</template>

<script>
import { Chart } from "@antv/g2";
export default {
 data() {
  return {
   year: [
    { year: "1991", value: 3 },
    { year: "1992", value: 4 },
    { year: "1993", value: 3.5 },
    { year: "1994", value: 5 },
    { year: "1995", value: 4.9 },
    { year: "1996", value: 6 },
    { year: "1997", value: 7 },
    { year: "1998", value: 9 },
    { year: "1999", value: 13 }
   ]
  };
 },
 mounted() {
  this.initLineChart()
 },
 methods: {
  initLineChart() {
   const chart = new Chart({
    container: "l1",
    autoFit: true,
    height: 500
   });
   chart.data(this.year);
   chart.scale({
    year: {
     range: [0, 1]
    },
    value: {
     min: 0,
     nice: true
    }
   });
   chart.tooltip({
    showCrosshairs: true, // 展示 Tooltip 辅助线
    shared: true
   });
   chart
    .line()
    .position("year*value")
    .label("value");
   chart.point().position("year*value");
   chart.render();
  }
 }
};
</script>
<style scoped>
</style>

示例代码

<template>
 <div>
  <div><h1 style="color: white">{{title}}</h1></div>
  <span>
   <div id="c1"></div>
   <div id="mountNode"></div>
  </span>
 </div>
</template>

<script>
  import G2 from '@antv/g2';
  export default {
    name: "spectaculars",
    data(){
      return{
        title:'地区货品跟进看板',
        basicColumnChartProp:{
          data:[{ genre: 'Sports', sold: 275 },
            { genre: 'Strategy', sold: 115 },
            { genre: 'Action', sold: 120 },
            { genre: 'Shooter', sold: 350 },
            { genre: 'Other', sold: 150 }],
          container:'c1',
          width:600,
          height:300
        },
        basicBarChartProp:{
          container:'mountNode',
          size:{'width':500,'height':300},
          data:[
            {
              country: '巴西',
              population: 18203
            }, {
              country: '印尼',
              population: 23489
            }, {
              country: '美国',
              population: 29034
            }, {
              country: '印度',
              population: 104970
            }, {
              country: '中国',
              population: 131744
            }
          ]
        }
      }
    },
    methods:{
      test:function () {
        const data = this.basicColumnChartProp.data;
        // Step 1: 创建 Chart 对象
        const chart = new G2.Chart({
          container: this.basicColumnChartProp.container, // 指定图表容器 ID
          width : this.basicColumnChartProp.width, // 指定图表宽度
          height : this.basicColumnChartProp.height // 指定图表高度
        });
        // Step 2: 载入数据源
        chart.source(data);
        // Step 3：创建图形语法，绘制柱状图，由 genre 和 sold 两个属性决定图形位置，genre 映射至 x 轴，sold 映射至 y 轴
        chart.interval().position('genre*sold').color('genre')
        // Step 4: 渲染图表
        chart.render();
      },
      basicBarChart:function () {
        let data = this.basicBarChartProp.data;
        let chart = new G2.Chart({
          container: this.basicBarChartProp.container,
          width:this.basicBarChartProp.size.width,
          height:this.basicBarChartProp.size.height
        });
        chart.source(data);
        chart.axis('country', {
          label: {
            offset: 12
          }
        });
        chart.coord().transpose();
        chart.interval().position('country*population');
        chart.render();
      }
    },
    mounted() {
      this.test();
      this.basicBarChart();
    },
    beforeCreate () {
      document.querySelector('body').setAttribute('style', 'background:#000000')
    },
    beforeDestroy () {
      document.querySelector('body').removeAttribute('style')
    }
  }
</script>

<style scoped>
