Question

是否可以更改StockEvent气球（提示）边框的颜色？它一直都是红色的。我找不到合适的选择。请参阅我当前的解决方案http://jsfiddle.net/a04j0hqv/4/ 当然有可能改变价值提示的AmBalloon边界，但似乎无法将其改为StockEvent。

您可以通过设置balloonColor property in stockEventsSettings：

来更改所有股票事件的气球颜色

regexp_replace(your_string ,'^[^- ]+ ?- ?', null, 1, 1)

很遗憾，您无法为每个不同的事件单独设置边框。

这是一个updated fiddle，气球设置为绿色。
