如何在Vue Echarts中创建饼图?

问题描述

我正在使用VueJS和Vue Echarts库来创建数据可视化。

这是Vue Echarts的Polar图的演示:

官方网站:https://ecomfe.github.io/vue-echarts/demo/ GitHub页面https://github.com/ecomfe/vue-echarts

<template>
<v-chart :options="polar"/>
</template>

<style>
/**
 * The default size is 600px×400px,for responsive charts
 * you may need to set percentage values as follows (also
 * don't forget to provide a size for the container).
 */
.echarts {
  width: 100%;
  height: 100%;
}
</style>

<script>
import ECharts from 'vue-echarts'
import 'echarts/lib/chart/line'
import 'echarts/lib/component/polar'

export default {
  components: {
    'v-chart': ECharts
  },data () {
    let data = []

    for (let i = 0; i <= 360; i++) {
        let t = i / 180 * Math.PI
        let r = Math.sin(2 * t) * Math.cos(2 * t)
        data.push([r,i])
    }

    return {
      polar: {
        title: {
          text: '极坐标双数值轴'
        },legend: {
          data: ['line']
        },polar: {
          center: ['50%','54%']
        },tooltip: {
          trigger: 'axis',axisPointer: {
            type: 'cross'
          }
        },angleAxis: {
          type: 'value',startAngle: 0
        },radiusAxis: {
          min: 0
        },series: [
          {
            coordinateSystem: 'polar',name: 'line',type: 'line',showSymbol: false,data: data
          }
        ],animationDuration: 2000
      }
    }
  }
}
</script>

结果: Polar Chart Looks Like

我想创建饼图而不是极地图。我检查了几个网站,但没有找到结果。

我需要的是: this pie chart

解决方法

签出https://github.com/ecomfe/vue-echarts/blob/master/src/demo/Demo.vue

您需要导入Pie lib,如下所示:

导入'echarts / lib / chart / pie'
