工作聊天示例： http ://www.highcharts.com/demo/dynamic-update/gray

我试图让上述工作，除了上面的图表填充了随机数据的修改；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。

到目前为止，我能够加载初始数据，以便它可以创建一个静态图表。为了使其静态，我不得不注释掉setInterval().

当我包含一些静态数据时，我在 Google Chrome ( ++ )setInterval()中的 JavaScript 控制台上收到错误消息。CtrlShiftJ

我不断收到错误：

未捕获的错误：NOT_FOUND_ERR：DOM 异常 8 highcharts.js:167

我不知道为什么？

第二个问题是由于异步性质，$.getJSON我可以使用与原始方法相同的方法获取数据，$.getJSON但在调用中调用它以setInterval()动态更新数据。
