如何使用fill true隐藏react-chart-js-2中的边框

npm install react-chartjs-2 chart.js

import React from 'react';
import { Line } from 'react-chartjs-2';

const chartData = {
  labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
  datasets: [
    {
      label: 'My Dataset',
      data: [65, 59, 80, 81, 56, 55, 40],
      fill: true, // 设置fill为true隐藏边框
      backgroundColor: 'rgba(75,192,192,0.2)',
      borderColor: 'rgba(75,192,192,1)',
      borderWidth: 1,
    },
  ],
};

class ChartComponent extends React.Component {
  render() {
    return (
      <div>
        <Line data={chartData} />
      </div>
    );
  }
}
