我使用的是AmCharts，除了導出以外，一切都正常。爲什麼AmCharts導出顏色變爲黑色和白色？
我使用下面庫AmCharts：
<link href="https://www.amcharts.com/lib/3/plugins/export/export.css" media="all" rel="stylesheet" type="text/css" />
<script src="~/Content/amcharts_3.20.9.free/amcharts/amcharts.js"></script>
<script src="~/Content/amcharts_3.20.9.free/amcharts/serial.js"></script>
<script src="~/Content/amcharts_3.20.9.free/amcharts/themes/light.js"></script>
<script src="https://www.amcharts.com/lib/3/plugins/export/export.js"></script>
和內部AmCharts.makeChart("chartdiv2", {我使用：
"export": {
"enabled": true
}`
我的圖表是默認豐富多彩這樣的：
但是我下載到PDF後， PNG，JPG等，或單擊Annotate...菜單選項圖表轉爲黑白（灰度）這樣的形象：
Here is video of this issue reproduced。

<div id="chartdiv2"></div>而問題的JSFiddle。
我已經在Google的Chrome和Mozilla的Firefox中測試了這種行爲請指導我如何修改此問題以使其更易於理解？我搜索了很多，但在網上找不到類似的問題。我真的很感激，如果amcharts.com支持也參與幫助。
如果可能請在https://jsfiddle.net/或類似的服務上提供示例。 –
我的代碼是寫在ASP.Net MVC和一些剃鬚刀是包括可以jsfiddle會理解我的代碼？ –
我從瀏覽器中生成的代碼製作一個JSFiddle我會回來一段時間的代碼，請稍等，謝謝 –
