amCharts angular 指令无法更改 ChartScrollbar 拖动手柄

Question

我似乎无法让 amCharts 尊重 ChartScrollbar 上的 dragIcon 属性。我有 a plunk here 证明了这个问题。

我怀疑这是 GrantMStevens amChartsDirective because of the previous problem I had with it not passing properties correctly and the fact that it works in this demo. The previous was debugged by xorspark 的问题，我能够复制他的调试，但这并没有以同样的方式被破坏。不幸的是，我还不够擅长调试 JavaScript 来追踪这个问题。

有人有什么想法吗？

  'use strict';

cdnjs 上旧的 3.13.0 版本的 AmCharts 不支持更改dragIcon。您需要使用更新的版本。最新版本的AmCharts库可以在AmCharts自己的CDN上找到：
