如何从react-chartjs-2的画布中删除垂直线？

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

const [chartData, setChartData] = useState({
  labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
  datasets: [
    {
      label: 'My Dataset',
      data: [65, 59, 80, 81, 56, 55, 40],
      fill: false,
      borderColor: 'rgba(75,192,192,1)',
      tension: 0.4
    }
  ]
});

<Line data={chartData} />

const handleRemoveVerticalLine = () => {
  const updatedChartData = {
    ...chartData,
    datasets: chartData.datasets.map(dataset => ({
      ...dataset,
      borderColor: 'rgba(0,0,0,0)' // 设置为透明色
    }))
  };
  setChartData(updatedChartData);
}

<button onClick={handleRemoveVerticalLine}>删除垂直线</button>
