前言

AntV-G2官网推荐使用Viser,本文介绍针对Vue版本的viser-vue简单使用。

安装viser-vue

yarn add viser-vue

yarn add @antv/data-set

main.js中引入

import Viser from 'viser-vue'

Vue.use(Viser)

定义d2demo.vue组件

<template>
 <div>
  <v-chart :forceFit="true" :height="height" :data="data" :scale="scale">
   <v-tooltip :showTitle="false" data-key="item*percent"/>
   <v-axis/>
   <v-legend data-key="item"/>
   <v-pie position="percent" color="item" :vStyle="pieStyle" :label="labelConfig"/>
   <v-coord type="theta" :radius="0.75" :innerRadius="0.6"/>
  </v-chart>
 </div>
</template>

<script>
const DataSet = require("@antv/data-set");

const sourceData = [
 { item: "学习", count: 40 },
 { item: "听歌", count: 21 },
 { item: "锻炼", count: 17 },
 { item: "游戏", count: 13 },
 { item: "发呆", count: 9 }
];

const scale = [
 {
  dataKey: "percent",
  min: 0,
  formatter: ".0%"
 }
];

const dv = new DataSet.View().source(sourceData);
dv.transform({
 type: "percent",
 field: "count",
 dimension: "item",
 as: "percent"
});
const data = dv.rows;

export default {
 name:'g2Demo',
 data() {
  return {
   data,
   scale,
   height: 400,
   pieStyle: {
    stroke: "#fff",
    lineWidth: 1
   },
   labelConfig: [
    "percent",
    {
     formatter: (val, item) => {
      return item.point.item + ": " + val;
     }
    }
   ]
  };
 }
};
</script>
