打开modal时echarts部分空白：

解决方法：使用ref绑定div，dom存在时再draw

javascript">           <div
              id="quintuple"
              style={{
                width: "450px",
                height: "350px",
              }}
              ref={modalRef}
            />

  const modalRef = (obj) => {
    if (obj) {
      drawChart(obj, [
        {
          value: [
            info.question || 10,
            info.theoretical_method || 10,
            info.practical_method || 10,
            info.effects || 10,
            info.conclusion || 10,
          ],
        },
      ]);
    }
  };

function drawChart(dom, data) {
  let myChart = echarts.getInstanceByDom(dom); //有的话就获取已有echarts实例的DOM节点。
  if (myChart == null) {
    // 如果不存在，就进行初始化。
    myChart = echarts.init(dom);
  }
  //此处省略数据处理过程
