我正在尝试上述工作，除了修改，其中上面的图表填充了随机数据;我希望使用$ .getJSON命令从非域数据库中提取数据并将其插入聊天中。
到目前为止，我可以加载初始数据，以便创建静态图表。为了使它静态，我必须注释掉setInterval（）的内容。
当我将setInterval（）包含一些静态数据时，我在Google Chrome中的JavaScript控制台上收到错误（Ctrl + Shift + J）。

我不断收到并且错误未捕获错误：NOT_FOUND_ERR：DOM 例外8 highcharts.js：167 我不知道为什么？
第二个问题是由于$ .getJSON的异步性质可以 使用相同的方法获取原始$ .getJSON的数据，但调用它 setInterval（）调用来更新动态数据。
