如何设置vue chartjs从零开始？

npm install vue chart.js

vue create Chart.vue

import { Bar, Line } from 'vue-chartjs'

export default {
  extends: Bar,
  mounted () {
    this.renderChart({
      labels: ['Red', 'Blue', 'Yellow', 'Green', 'Purple', 'Orange'],
      datasets: [
        {
          label: 'Data One',
          backgroundColor: '#f87979',
          data: [40, 20, 30, 50, 10, 70]
        }
      ]
    })
  }
}

<template>
  <div>
    <chart></chart>
  </div>
</template>

<script>
import Chart from './Chart.vue'

export default {
  components: {
    Chart
  }
