我想在调整图表大小时使其具有响应性。我正在使用两个图表库来处理具有响应网格布局的图表。（1）重新绘制React图表（2）react highcharts我的react recharts调整工作正常，他们是响应的，但highcharts没有响应，当我尝试调整他们的大小，他们保持不变。有人能帮助我吗？下面是代码。这是我的react网格布局代码。也看图表图像。在调整大小这个空白区域应该填充图表宽度。

I fixed the issue . i simply import the highcharts in attendance.js file 
then in onLayoutChange function i write this code .
  const onLayoutChange = (_, allLayouts) => {
    setLayouts(allLayouts);
    for (let i = 0; i < Highcharts.charts.length; i += 1) {
      if (Highcharts.charts[i] !== undefined) {
        Highcharts.charts[i].reflow();
      }
    }
  };

then call this function in react-grid-layout onLayout change
        onLayoutChange={() => onLayoutChange()}
. i am posting answer if anyone else stuck with the same issue. because while working with highcharts in react-grid-layout you gonna face this issue. reason is reflow which highcharts mentioned in their documentation. 
if anyone have more better approach please write your answer.
