如何在React中使用highcharts的charts.get(位置)？

npm install highcharts
npm install highcharts-react-official

import React from 'react';
import Highcharts from 'highcharts';
import HighchartsReact from 'highcharts-react-official';

class ChartComponent extends React.Component {
  constructor(props) {
    super(props);
    this.chartRef = React.createRef();
    this.state = {
      chart: null
    };
  }

  componentDidMount() {
    const chart = this.chartRef.current.chart;
    this.setState({ chart });
  }

  render() {
    const options = {
      // Highcharts配置选项
    };

    return (
      <div>
        <HighchartsReact
          highcharts={Highcharts}
          options={options}
          ref={this.chartRef}
        />
      </div>
    );
  }
}

handleButtonClick = () => {
  const chart = this.state.chart;
  if (chart) {
    const position = chart.get(位置);
    console.log(position);
  }
}

render() {
  // ...
  return (
    <div>
      {/* 其他组件内容 */}
      <button onClick={this.handleButtonClick}>获取位置</button>
    </div>
  );
}
