我想在饼图中显示label的值。(vue-chartjs / pieceLabel)

npm install vue-chartjs piece-label

import { Pie, mixins } from 'vue-chartjs';
import pieceLabel from 'chartjs-plugin-piechart-outlabels';

const { reactiveProp } = mixins;

components: {
  Pie
},

mounted() {
  this.renderChart(this.chartData, this.options);
},

data() {
  return {
    chartData: {
      labels: ['Label 1', 'Label 2', 'Label 3'],
      datasets: [
        {
          data: [10, 20, 30],
          backgroundColor: ['#FF6384', '#36A2EB', '#FFCE56']
        }
      ]
    },
    options: {
      plugins: {
        pieceLabel: {
          render: 'label',
          fontColor: '#fff',
          precision: 0
        }
      }
    }
  };
},

<template>
  <div>
    <pie :chart-data="chartData" :options="options"></pie>
  </div>
</template>
