如何在React Highcharts中向自定义按钮添加导出功能? [英] How to add export functionality to custom button in React highcharts?

问题描述

我有一个项目，我试图在该项目中从图表的外部实现导出Highchart功能.

I have this project in which I am trying to implement export highchart functionality from out side of the chart.

有什么办法可以实现?我正在使用React highcharts，下载格式为Jpeg和CSV.

Is there any way I can achieve that? I am using React highcharts and the download formats are Jpeg and CSV.

预先感谢

推荐答案

我找到了使用功能组件的解决方案:

I found an solution using functional components:

首先导入模块:

import * as Highcharts from 'highcharts';
import HighchartsReact from 'highcharts-react-official';

require('highcharts/modules/exporting')(Highcharts);
require('highcharts/modules/export-data')(Highcharts);

然后创建对图表的引用:

Then create a ref to the chart:

  const chart = useRef();
....
....
<HighchartsReact ref={chart} highcharts={Highcharts} options={chartOptions} />

然后创建一个由click事件触发的方法，就像这样:

Then create a method like this one, triggered by a click event:

  const downloadCSV = () => {
    if (chart && chart.current && chart.current.chart) {
      chart.current.chart.downloadCSV();
    }
  };
